Device simulation program specialized for semiconductor lasers in two dimensions (formerly LASTIP)
<Main Features> ■ Simulation software for semiconductor lasers based on a two-dimensional structural model ■ Calculations can be executed more lightly as effects in the resonator direction are not included ■ Convergence is smoother as the finite element calculation mesh is also set in two dimensions <Diverse Physical Models and Functions> ■ Light output-current (L-I) characteristics ■ Current-voltage (I-V) characteristics ■ Two-dimensional potential, electric field, and current distribution ■ Two-dimensional distribution of electron and hole density ■ Band diagrams under various bias conditions ■ Two-dimensional distribution of occupancy and density of deep level traps in semiconductors ■ Two-dimensional optical field distribution of multiple transverse modes ■ Two-dimensional local optical gain distribution ■ Mode-dependent refractive index dependence on bias current ■ Mode-dependent gain and refractive index change dependence on bias current ■ Dependence of spontaneous emission spectrum on current ■ Far-field distribution ■ Time evolution (transient model) and temperature dependence (uniform temperature) of all the above quantities ■ For other features and details, please download the catalog or contact us. ■ If you wish to try a trial version, please contact us using the information below.
