Photonics Group
Photonics Group is constituted by a few the talented people, who deal with the computer simulation and modeling physical phenomena in photonic structures. Our interest is focused on the semiconductor devices
- edge-emitting laser diodes,
- surface-emitting laser diodes,
- laser matrices,
- resonant cavity photodetectors.
Our computer models cover complexity of
- optical phenomena,
- electical phenomena,
- thermal phenomena,
- gain,
- oxidation kinetics,
- mechanical stress
in the lasers emitting in a visible spectrum of wavelength, as well as in infrared or ultraviolet ranges.
In particular, we deal with:
- 3D computer simulation of edge-emitting and vertical-cavity laser diodes and LEDs of different types taking into account mutual interactions between thermal, electrical and optical phenomena, gain and mechanical stress,
- investigation of heat-generation processes and heat flow in vertical-cavity and edge-emitting laser diodes and LEDs of different types,
- investigation of thermal, electrical and optical, mechanical and gain interactions between elements of 1D and 2D diode laser arrays,
- analysis of gradual and catastrophic degradation processes in laser diodes; analysis of physical mechanisms of degradation,
- theoretical analysis of thermal conductivity of ternary and quaternary AIIIBV compound semiconductors,
- efficiency optimisation of lasers and high power laser arrays designs,
- modeling of oxidation kinetics AlAs layers during manufacturing of laser and LED devices,
- analysis of electromagnetic field in photonic band bap materials and its application to the light-emitting devices.
