Principal Photonic Engineer
CurrentI work on passive and active integrated photonic device development on the silicon and III-V material platforms. I focus on the development of photonic test systems, including the hardware, software, and analysis routines that are required. Automated test routines are conducted on single passive and active devices, that combine electrical and optical characterisation along with larger-scale circuit level-analysis.My skill include the building of automated photonic/electronic test platforms, using a wide variety of electrical test and measurement apparatus under the control of python-based software. I am adept at using tools such as pyvisa and PyQt for instrument control in custom-made multi-threaded applications.The analysis of my results is primarily undertaken using python, and I make extensive use of analytical compact models for the efficient characterisation of devices given experimental data from a limited number of parameter-sweeps. I often work at the interface between the optical and electrical domains, and have developed electro-optic models of devices for use in electronic Spice models. I am skilled in the analysis of large data sets, and the deduction of meaningful insights from these.In addition to my work on photonic testing, I have also developed passive photonic components. This has included mode-based simulations of broadband directional couplers, simulations of thermal phase modulators and grating couplers.
