Introduction to various options and physical models of the semiconductor LD and optical device 3D simulator PICS3D.

■A demo video of the "Trial Guide" is currently available on the YouTube link below! ■To request a trial version, please use the "Trial Version Application Form." (For product details, please refer to the catalog or contact us.)

<Main Features> ■ Suitable for the design and analysis of devices where the effects in the resonator direction are important. ■ Lasers including diffraction gratings such as DFB, DBR, and VCSEL can be calculated using mode coupling theory and multilayer film optical theory. <Diverse Physical Models and Functions> ■ Coupling coefficients of waveguides and gratings (first-order and second-order gratings). ■ Longitudinal carrier density distribution, optical gain, and light intensity for the main and side longitudinal modes. ■ Calculation of surface emission mode distribution for second-order grating DFB lasers. ■ Output and frequency variation for different longitudinal modes. ■ Side mode ratio, linewidth, product of linewidth and output, effective alpha, second harmonic distortion, surface emission output (second-order grating DFB). ■ Mode output spectra under different laser surfaces and arbitrary bias conditions. ■ Mode output spectra under different bias conditions and over time. ■ AM/FM small signal modulation response and FM/RIN noise spectrum under arbitrary bias conditions. ■ Second harmonic distortion spectrum. ■ For other functions and details, please download the catalog or contact us. ■ If you wish to request a trial version, please contact us using the information below.
