HAROLD is an advanced hetero-structure simulator for modelling Fabry-Perot quantum well lasers with near-arbitrary vertical structure and layer compositions. It is based on well-established physical models which account for a large number of physical processes, thus enabling one to obtain a very comprehensive set of simulation results by which one can test and improve one’s laser designs. Devices can be simulated in both 1D (vertical) and 2D (vertical-longitudinal), operating under pulsed (isothermal) or CW (self-heating) conditions. An additional XY Laser Module allows one to perform 2D lateral-vertical (XY) simulations starting from a full physical description of the laser’s cross-section. The cross-section can include graded etching and insulating layers, and have n and p-contacts on the same side. This ideal for studying the effects of lateral structure in both ridge waveguide lasers and SOI hybrid lasers. The Harold EAM Module includes a Quantum-Confined Stark Effect (QCSE) model allowing you to model electro-absorption modulators and electro-refractive modulators. As well as being a laser simulator in its own right, Harold can export material models to Photon Design’s circuit simulator, PICWave, thereby allowing results from its detailed physical model to be incorporated into larger, more complex devices for fast simulation in the time domain.
Advanced hetero-structure model for simulating FP lasers/SOAs based on well-established physical models:
self-consistent solving of electro-optic, heat flow, carrier capture/escape and recombination equations
supports strained layers
built-in optical mode solver
built-in Schrodinger solver
Layers editor allows near-arbitrary (single and MQW) epitaxial layer structures to be defined; supports grading of alloy composition and doping within layers.
Material database: comes with a set of standard materials; you can add your own materials too.
