Today’s fiber-optic communication systems are facing significant challenges with regards to energy consumption. To counteract this, lightwave communication systems will increasingly rely on photonic integrated circuits (PICs). PICs bring many beneficial features such as miniaturization, stability and the possibility for low-cost fabrication. They will be crucial in the future for establishing greener and faster communication links. 

This project will investigate 3D photonic integrated circuits for coherent optical communications. The project will explore both, the existing erbium band as well as the emerging band in the 2 micrometer window enabled by thulium fiber amplifiers. The project has obtained financing by the prestigious European Research Council through a Consolidator grant.


:: On chip optical spectroscopy>>

Laser spectroscopy is an invaluable technique for unravelling the atomic and molecular structure of matter. It is a widely used diagnosis tool in several industrial applications, such as the monitoring of combustion processes, remote sensing of greenhouse gases and pharmaceutical quality control. 

A laser frequency comb is a special type of laser that holds great promise for precision spectroscopy because it allows to probe multiple species at once. This project will investigate a new and emerging laser frequency comb platform on a chip, the so-called microresonator comb, for applications in spectroscopy. This technology could enable precision spectroscopy in a portable and robust platform that renders more suitable for “real-life” applications outside the well-controlled laboratory environment. The project will be done in close collaboration with the RISE institute in Borås and the laser company Thorlabs in Mölndal. 

The laboratory 

The Photonics laboratory at the Microtechnology and Nanoscience Department (MC2) is a dynamic and creative group with about 30 members working in an international and collaborative atmosphere. We perform both curiosity-driven and applied-research in the areas of optoelectronics, nanophotonics, and fiber optic systems. We enjoy a state-of-the-art laboratory for fiber-optic communications and have access to in-house cleanroom facilities to manufacture photonic devices.




Postdoc position available at the Czech Technical University in Prague, Czech Republic.


Research project focus:

In the framework of the project, optical fibers will be studied with respect to one or more of of selected areas: hybrid free-space optics/fiber networks, analogue signal transmission for radio-over-fiber systems and last but not least photonic crystal fibers for ultra-stable lasers and nonlinear applications. Analyses, simulation and especially experimental verification will be performed to determine optimal solution for specific fiber system development. Knowledge of simulation tools (COMSOL, Zemax) is an advantage. Practical experience with fiber tapering, lensed fibers, specialty optical fiber and their splicing will be great.


Requirements for postdocs:

1. A PhD awarded after Nov. 19, 2010.

2. At least 2 journal papers published between Nov 20, 2014 and Nov 20, 2017 registered in WoS, Scopus or ERIH databases.

3. Research job or PhD study outside the Czech Republic for at least 2 years in the period between Nov 20, 2014 and Nov 20, 2017.


Selected topics for Postdoc position:

1. Specialty optical fibers, modified structures, coupling aspects, solid-coupling for various applications.

2. Optical fibers for hybrid networks (FSO+fiber, VLC+fiber), coupler design, WDMs, lensed fibers for specific experiments.

3. Microwave photonics based on hollow-core and other specialty optical fibers.

Experimental Postdoctoral Position in ultrafast X-ray science: the Physical and Chemical and applied Spectroscopy Group (C-PCS) in collaboration with the Laboratory for Ultrafast Materials Optical Science (LUMOS) is seeking outstanding candidates to join our efforts in nonlinear X-ray optics and materials with a focus on developing novel methods of characterizing soft and hard ultrashort X-ray pulses. This work will involve participation in developing a unique, high intensity source of soft X-ray pulses based on high harmonic generation using an intense Ti:Sa laser system. The soft X-ray pulses will be used for ultrafast spectroscopy experiments to investigate the nonlinear light-matter interaction at soft X-ray frequencies and also for novel methods of characterizing soft and hard X-ray pulses using visible cameras. This position will likely also include the opportunity to carry out experiments at an X-ray Free Electron Laser. The postdoc will be part of a one-of-a-kind collaborative environment consisting of accomplished scientists in ultrafast spectroscopy, materials science, laser physics, condensed matter physics theory and materials synthesis. Some information on research projects and capabilities at LUMOS is available at http://cint.lanl.gov/facilities/LUMOS/.

What You Need              

Minimum Job Requirements:  Strong hands-on, experimental background in one or several areas from the following list (preferred in this order): high harmonic generation, high intensity ultrafast lasers, ultrafast spectroscopy and/or ultrashort pulse characterization. Demonstrated ability to work productively on multiple tasks with minimal supervision. Demonstrated experience in gathering and interpreting technical data.

Desired Skills:  Knowledge of ultrafast laser systems (titanium-sapphire) and high power ultrafast systems, Q-switched YAG lasers, UHV equipment, LabVIEW software and programming, solid-state physics, nonlinear optics, and experience working at X-ray free electron, synchrotrons, or with other X-ray sources. Excellent written and oral communication skills, and the ability to work in a Team environment.

Education:   A Ph.D. completed within the last five years or soon to be completed is required.

Notes to Applicants:  In addition to applying online on the LANL jobs site, please email a copy of your CV and cover letter, or any questions to Pamela Bowlan (pambowlan@lanl.gov) and Richard Sandberg (sandberg@lanl.gov).

 Where You Will Work

Located in northern New Mexico, Los Alamos National Laboratory (LANL) is a multidisciplinary research institution engaged in strategic science on behalf of national security.  LANL enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.


High-peak power compact femtosecond lasers allow strong-field interactions that are the basis for high-precision laser micro-fabrication. They also create extreme conditions within the matter, leading to the generation of rainbow light used to produce even shorter pulses and new frequencies that can extend from the X-ray to the TeraHertz domain. However, due to the low conversion efficiencies, these attractive light pulses remain unexploited in the context of laser nano-/micro-fabrication.

The main objective of this project is to exceed the intrinsic limits of ultrafast laser material processing by developing novel seeded-control technologies with extreme light pulses. In the proposed concept, seed free carriers are injected into materials from extreme light and then avalanched with perfectly synchronized infrared pulses to extract all potential benefits from modest energy new types of radiation.

The project includes the study of interactions seeded with deep-ultraviolet, few-optical-cycle and mid-infrared ultrashort pulses. The expected nonlinear processes with these radiations open new and exciting opportunities to tailor material properties with nanometer-scale spatial resolutions and in the three dimensions (3D) for materials inside which the occurrence of breakdown is, today, nearly inaccessible (e.g. semiconductors). The latter must lead to the first demonstrations of rapid 3D prototyping by laser of silicon photonics microdevices.

A long term objective is to open the door to the use of the most extreme ultrashort laserinduced radiations, including extreme-ultraviolet attosecond pulses that hold promises to reach the highest degree of control in the time and space of the interactions. These and other ideas require investigations on ionization physics by ultrashort pulses at extreme wavelengths. They also require tight control of the ultrafast pulses, broadband manipulations and novel interaction diagnostics technologies that will be developed as parts of the project to extract all potential benefits from modest energy new types of radiation. 

We are looking for PhD candidates to be part of this ERC funded project.
