TomReep
Tom Reep received his BSc and MSc in Electrical engineering at Eindhoven university of technology (TUe) in 2019 and 2021 respectively. During his master thesis he looked into widely tunable lasers for optical coherence tomography on the InP platform and did an internship at imecs life-science technology group looking at the use of silicon photonics for life-science applications.

Currently he is working on integrating graphene modulators into integrated mode-locked lasers using saturable absorption effects of 2D materials. Furthermore he is working on transfer-printing of amplifiers and III/V saturable absorbers on SiN and the SOI platform for heterogenous (mode-locked) laser applications.
