Crosslight Software Tutorial on Optoelectronic Device Simulation
Friday, 28 July 2017, 13:00-16:30
Technical University of Denmark, Lyngby Campus
Instructor: Joachim Piprek
This hands-on tutorial is free of charge, however, seating is limited and pre-registration is required. Participants are encouraged to bring a laptop PC with pre-installed Crosslight software. To register for the tutorial and the free software trial license, please e-mail your contact information to piprek(at)nusod.org. You will receive detailed instructions on how to install the software on your laptop in the week before the conference.
The tutorial gives a hands-on introduction to high-end simulation tools for electronic and optoelectronic devices (APSYS & PICS3D by Crosslight Software Inc., see below). These software packages combine electrical, thermal, optical, and quantum-mechanical models in two or three dimensions. They can be applied to a large variety of semiconductor devices such as laser diodes, light-emitting diodes, solar cells, photodetectors, modulators, amplifiers, and transistors. The workshop demonstrates software operation and simulation strategies using realistic device examples. Physical models and material parameters are explained and methods for obtaining realistic simulation results are discussed.
APSYS: 2D/3D simulation of non-lasing devices. Features include: hot carrier transport, quantum mechanical tunneling, multi-quantum well structures, k·p band structure calculation, selfconsistent Poisson and Schroedinger equations solving, wave guiding in media with arbitrary complex refractive index distribution, transient models, small ac-signal analysis, interface and bulk charge trapping, piezoelectric effect, impact ionization, optical absorption and emission with exciton, and other many-body phenomena, LED ray tracing model to optimize device structure and packaging for light extraction efficiency, photon recycling effect, different relaxation models. Broad range of semiconductor devices, including classical or quantum-mechanical resonant tunneling diodes, bipolar and field effect transistors, LEDs, solar cells, detectors, semiconductor optical amplifiers, electro-absorption modulators.
PICS3D: 2D/3D simulation of edge-emitting lasers (FP, DFB, DBR) and vertical-cavity laser diodes (VCSELs). It includes the 2D laser simulator LASTIP but it can also be used for waveguide photodetectors, semiconductor optical amplifiers, photo-pumping, and coupling to external passive optical components, i.e. external gratings (1st and 2nd order). PICS3D can calculate longitudinal distribution of carrier density, gain, optical field, and surface emission modes for 2nd order grading DFB. In addition to steady (dc) L-I, or I-V characteristics, it can be used for ac, and transient analysis of laser diodes, mode emission power, spectrum and chirp analysis, AM and FM small signal modulation response, and second harmonic analysis. It may include 3D current flow, vectorial waves, Poisson and Schroedinger Equations self-consistent solution in complex MQW with piezo-electric fields, and quantum-mechanical tunneling.
