Extraction of Laser Rate Equation Parameters
This shows the use of the Laser Parameter Extractor module in extracting a set of laser rate-equation parameters based on nonlinear fitting of measured laser characteristics. The extracted parameters are suitable for use with, and can be passed on automatically to, the LaserSM_RE module.

Measuring Mode Partition Noise in Fabry-Perot Lasers
This demo shows measurement of the Mode Partition Noise in a Fabry-Perot laser by examining the RIN spectra for the total laser emission and for the dominant mode alone. This noise is caused by considerable low-frequency fluctuations of the individual lasing modes powers (including the dominant mode alone) in comparison with the fluctuations of the averaged total laser power.

MQW Laser Characterization with TestSetLaser
This demo shows, how characteristics of a laser could be measured employing LaserCharacterizer cosimulation galaxy. This module allows to measure a light-current dependency (L-I curve), an intensity modulation (IM), frequency modulation (FM) responses to a small modulating signal and corresponding phase responses. All characteristics as well as modulating electrical and output optical signals could be visualized.

Characterization of Relative Intensity Noise (RIN) in Lasers
This shows how the Relative Intensity Noise (dBc/Hz) of a laser can be determined as a function of RF frequency. Usually the RIN has a resonant peak at the same frequency as the carrier-photon resonance of the laser. The RIN characterization uses demo module "RIN_Analyzer". This module is based on Python cosimulation and can be used as a template for creating your own instrumentation tools.
