Photon Design provides laser design and simulation training on JePPIX PIC Design Course
Photonic simulation CAD software developer Photon Design Ltd of Oxford, UK has provided laser design and simulation training on the JePPIX ‘PIC Design Course’ 2025, held at Eindhoven University of Technology (TU Eindhoven) on 27 October to 7 November.
As the Joint European Platform for Photonic Integration Components and Circuits (an association of commercial enterprises, research organizations and universities serving as a platform for promoting integrated photonics on a European level), JePPIX is a modular, integrated silicon photonics platform that enables a fast, efficient, accurate and compact manufacturing approach, which helps to increase production capacity; essential to meeting increasing demand for photonics devices in multiple markets. The JePPIX training course provided photonics engineers with the theory and practice of photonic integrated circuit (PIC) design, using indium phosphide (InP) technologies on its platform. The design of photonic components (such as amplifiers, lasers, modulators and detectors) was covered, along with PIC design, layout and simulation using process design kits (PDKs), and practical design for foundry manufacture and multi-project wafer (MPW) runs.
“Our hands-on approach required attendees to design a taper laser comprising III-V epi substrate on SOI (silicon on insulator),” says Photon Design’s scientific and technical advisor Alex Edwards. “Our FIMMPROP simulator showed attendees how quickly a taper design could be produced, complete with dynamic step sizing. Reflective Bragg gratings and other periodic structures were simply repeated, before performing a ‘length sweep’ to determine the laser’s adiabatic length. An active PIC simulation was then generated using our PICWave tool,” he adds.
“FIMMPROP is an EME-based laser simulator that processes far faster than standard FDTD alternatives. It provides equivalent results regardless of device size, whether the taper is 40μm or 400μm. All simulations were run locally on a regular laptop, showing both the simplicity and speed of EME. In contrast, many FDTD solutions are growing to rely on costly, outsourced cloud processing service for each simulation run which, during the design phase, can occur many times.”
