HAROLD
HAROLD Fabry-Pérot (FP) quantum well laser design software
It is an advanced heterostructure simulator for modeling Fabry-Pérot and VCSEL quantum well lasers. Calculations can be performed in both 1D and 2D, allowing for 2D transverse (XY) calculations of laser cross-sections and the effects of lateral structures in both ridge waveguide lasers and SOI hybrid lasers. - XY Module It can perform 2D transverse (XY) simulations. The cross-section can include stepped etching layers and insulating layers, making it ideal for studying the effects of lateral structures such as ridge waveguide lasers and SOI hybrid lasers. - EAM Module Calculations can include a quantum confined Stark effect (QCSE) model, allowing for the computation of electro-absorption modulators and electro-refractive modulators. - VCSEL Module It is capable of calculating multiple optical resonator modes, electric drift diffusion, thermal flow, and electron-photon interactions in a complete 3D model. It provides a comprehensive integrated design environment for various VCSEL variations, including QW materials and current blocking.
