FIMMWAVE 7.2 is released

FIMMWAVE We are pleased to announce the release of FIMMWAVE version 7.2.0, which includes the introduction of Euler Bend Sections, Expression Bend Sections and the ability to specify a z-dependent curvature in Planar Sections and Taper Sections. As such, it is now possible to model a wide variety of bent waveguide structures without the need for scripts.

PICWave 6.0 is released

We are pleased to announce the release of PICWave version 6.0 - This features an improved user-interface making it easier to manage multiple windows and editing of properties; a complex mode solver option for modelling lossy/leaky waveguides; support for analytic S-matrix spectra for defining passive component models by mathematical expression rather than tabulated data; and numerous other improvements and bug-fixes! .

Harold VCSEL

Photon Design has been invited to write an article about VCSEL design in the magazine Compound Semiconductor. Read the article here: Compound Semiconductor Vol. 26(4) (page 34)

Harold/VCSEL is now multi-mode! This challenging and significant advance in VCSEL modelling provides an important leap forward in VCSEL design.

OmniSim 7.2 is released

OmniSim version 7.2.0 adds support for GDSII file import, import and export of beam profile in Zemax and FRED file format.

EPIPPROP 3.2 is released

EPIPPROP version 3.2 contains a completed command-line interface, allowing you to control the design stage via scripting. The AWG module allows random phase variations through each waveguide to simulate slight variations in the refractive indices and geometric properties of the AWG.

FIMMWAVE and FIMMPROP Online Training - May 2022

Photon Design will be hosting an online training course for FIMMWAVE and FIMMPROP on the 24th and 25th of May for Europe and Asia, and the 26th and 27th of May for North and South America. Taking place in two 4 hour sessions over two days this training is aimed at both beginners and experienced users and aims to help you get the most out of FIMMWAVE and FIMMPROP. Please email us for more information or if you would like to register.

Harold 6.0/VCSEL – New!

Photon Design is pleased to announce it’s comprehensive VCSEL model. Building on our 25 years’ experience in optical and laser diode modelling, this is a full 3D model covering the optical mode, current flow, drift/diffusion, QW gain, thermal flow. It produces LI curves, profiles of carriers/current/temperature, quantum efficiency, spectra, linewidth, far-field results and more. Later versions will also model dynamics.

Harold 6.0 also includes useful improvements to its other modules, including: a thermionic emission model for its 1d gain module, improved material data and additional command-line functionality.
