MODELING AND SIMULATION OF VERTICAL CAVITY SURFACE EMITTING LASERS

Vertical Cavity Surface Emitting Laser SFP

The vertical-cavity surface-emitting laser (VCSEL / ˈvɪksəl /) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also called in-plane lasers) which emit from surfaces. Unlike traditional edge-emitting lasers, VCSELs emit the laser beam vertically, revolutionizing optical communication and optoelectronic technology. Since their commercial introduction in the 1990s, VCSELs have transformed multiple.

The surface emission from a bulk semiconductor at ultra-low temperature and magnetic carrier confinement was reported by Ivars Melngailis in 1965. The first proposal of short VCSEL was done by Kenichi Iga of Tokyo Institute of Technology in 1977. Contrary to the conventional Fabry-Perot edge-emitting semiconductor lasers, his invention comprises a short laser cavity less than 1/10 of the edge-emitting lasers vertical to a wafer s.

Optically pumped wavelength-tunable vertical-cavity surface-emitting lasers (VCSELs) operating in the ultraviolet A (UVA) spectrum were demonstrated.

Laser Diode Simulation Parameter Representation

Laser simulation is implemented as part of the Atlas device simulation framework Atlas provides framework integration Blaze provides III-V and II-VI device simulation Laser provides optical emission capabilities for edge-emitting lasers VCSEL p. III-V Device Simulation maturity has conventionally lagged behind silicon leading to many immature standalone tools with a low user base Users must ensure that the simulator they evaluate has all the necessary components Blaze shares many common components of the Atlas framework with the mature and heavily used silicon simulator, S-Pisces Blaze i. Blaze uses currently available material and model coefficients taken from published data and university partners For some materials often very little literature information is available, especially composition dependent parameters for tenrary compounds Some parameters (eg. Process simulation Internal Atlas syntax limited to rectangular structures Standalone device editor (DevEdit) GUI to define structure, doping and mesh batch mode for experimentation abrupt and graded mole fraction definition non-rectangular regions supported Structure Creation Using DevEditLaser works within the framework of Atlas and Blaze. Blaze provide electrical simulation of heterostructure devices and material models for common III-V and II-VI semiconductors Self-consistently solves the Helmholtz equation to calculate optical field and photon densities Accounts for carrier recombination.

Bus Relay Protection Simulation Experiment

This project simulates an impedance-type distance relay for protecting a 220 kV transmission line using MATLAB/Simulink. The relay detects faults by measuring line impedance and operates in three zones (Z1, Z2, Z3) with configurable time delays. The simulation includes:Consideration is given to availability and location of breakers, current sensing devices, and disconnect switches, as well as bus-switching scenarios, and their impact on the selection and application of bus protection.
