OmniSim and CrystalWave version 4.5 released

The latest version of OmniSim and CrystalWave has been released. It is available as a native 64-bit application, allowing you to use as much memory as your computer can support! The FDTD Engine now supports SMP (symmetric multi-processing), allowing you to take advantage of the multi-core capabilities of your computer to speed up your calculations and model larger devices with finer accuracy.

PICWave version 3.1 released

New features include: passive dispersive waveguide sections, fibre waveguide cross-sections, connections between electrodes, grating apodisation, a thermal model for junction heating, and the automatic calculation of spontaneous emission numerical aperture. Furthermore, the wavelength dependent scattering matrices of components with multiple modes/ports can now be imported (e.g. from FIMMPROP) and improvements have been made to the method used to obtain equivalent time-domain responses. New analysis tools include: group delay and dispersion spectra, and longitudinal profiles of electrode state (voltage/current).

FIMMWAVE version 5.2 released

The latest version of FIMMWAVE and FIMMPROP features considerable improvements: FIMMPROP can now launch an input mode with any tilt angle and curvature - ideal for the modelling of ring couplers! The design interface for planar devices has been considerably improved, and now allows you to design arbitrary z-varying sections - including ring waveguides - even more easily. Speed of calculation has been significantly improved, in particular for tapered structures.

Harold Version 4.3 released

Harold, Photon Design's heterostructure laser model, including self consistent Schroedinger/drift/diffusion solutions, gets a significant upgrade. The new version now boasts a sophisticated capture escape model, temperature dependent mobility and many more. Harold, together with PICWave, form a highly sophisticated laser/SOA model capable of efficiently modelling the details of the quantum well, while at the same time dealing with complex macroscopic structures such as multi-section sampled-grating tunable lasers.
