Current communication networks rely on optical fibres to sustain the constant increase in data rate driven by the perpetual growth of Internet traffic. In order to efficiently utilize optical fibres, it is critical that the spectral efficiency of optical communication systems keeps improving to match the increasing demand for high-speed information exchange.
In optical communications, however, the nonlinear properties of optical fibres cause distortion to the signal and no clear solution tackling the problem has yet been found.
Several approaches have been proposed mainly relying either on all-optical or electrical solutions to either mitigate or compensate the signal distortion.

Today's communication infrastructure is facing serious scalability and energy consumption issues, and it will be unsustainable in a not too distant future, if there are no changes in energy consumption trends. The adoption of nano-photonic devices and particularly nano-laser structures can potentially enable dramatic changes to fundamental working principles and power budgets of optical data transmitters.
The research center NATEC (NAnophotonics for TErabit Communications) is exploring novel nano-photonic devices for optical communication. In particular, a novel laser structure based on the Fano resonance in a nano-cavity is showing extremely attractive properties in terms of modulation speed and power efficiency.
The topic of this PhD project is to investigate the applications of the Fano laser and other nano-photonic structures to optical communication systems.

The Department of Photonics Engineering at the Technical University of Denmark has an open PhD position in the project “Two-photon Selective Plane Illumination Microscopy through Fibres (T-SPIF)”. The subject of the project is at the cutting edge of science and will involve collaboration with international experts and industry.
For many human diseases, early diagnosis is crucial for a positive therapy outcome, but would require techniques for fast microscopic imaging of tissues inside the body at a resolution level of individual cells.
In this project, you will explore, theoretically and experimentally, methods of shaping both spatial and temporal beam and phase profiles of ultrafast pulses of laser light using a spatial light modulator (SLM), to generate a light sheet at the distal end of either a multimode or multicore fibre.

The Fiber Sensors & Supercontinuum Group at DTU Fotonik, Department of Photonics Engineering at the Technical University of Denmark is seeking a PhD student for a 3-year Scholarship in the field of image processing software for Optical Coherence Tomography (OCT) systems operating in the mid-infrared.
The position is funded by the project "Spectrally shaped supercontinuum sources for high-resolution Optical Coherence Tomography medical imaging and non-destructive testing" (ShapeOCT).
ShapeOCT will use Danish strongholds in supercontinuum (SC) light source and photonic crystal fiber (PCF) technology to develop a new generation of SC light sources with shaped noise and power spectra that are optimal for use in a new generation of ultra-high resolution Optical Coherence Tomography (UHROCT) systems.
