Dr. Mario Chemnitz leads the “Smart Photonics” Junior Research Group at the Leibniz Institute of Photonic Technology (Leibniz IPHT). The group investigates the application potential of programmable optical devices in combination with machine learning algorithms and nonlinear photonics. The research focuses on a better understanding how to utilize complex wave dynamics in fibres and waveguides for unusual optical transformations, information encoding, and programmable processing. Building on this knowledge, the research group thrives for exploring new imaging and sensing solutions, new nonlinear states of light, and neuromorphic (brain-like) processor hardware. With this interdisciplinary approach at the interface of fundamental and applied MINT sciences, the research group contributes to the worldwide search for the next generation of energy-saving information processors for future medical diagnostics, telecommunications, and green computing.
Dr. Chemnitz focuses on
- the development of programmable optical fibers and waveguide systems
- identification and utilization of new types of solitary states and phenomena emerging from strong non-local nonlinearities, mainly in liquid-core optical fibers
- understanding nonlinear optical processes as means to compute dense multi-dimensional optical information
- optical system interfacing and automization towards big-data measurements and information processing
- development of hyperspectral sources and integrated optics for ultrafast sensing and imaging
- to be confirmed
Research Methods and Equipment
The optical laboratories run by Dr. Chemnitz offer a variety of programmable devices, fiber components, lasers, and optical diagnostics, mainly operating in the telecom wavelengths domain (i.e. Erbium C- and L-band, 1500-1600nm). All devices, commercial as well as custom made, are intended to be fiber-coupled offering a low entrance level for newcomers to optics.
- Arbitrary spectral amplitude and phase filters
- RF function generators and optical fiber modulators
- Femtosecond frequency comb sources and optical amplifiers
- Ultrashort pulse diagnostics, incl. autocorrelation, FROG, RF and optical spectrometers
Through close collaboration, the group has further access to chemical labs, fiber technologies (e.g., fiber drawing tower, fusion splicers and tapering machines), as well as optical characterization techniques (e.g., commercial supercontinuum sources, ellipsometers, microscopes).
