Build the future of advanced, miniaturized spectroscopy systems for health and environment monitoring.
One attractive method for using OFCs in health and environmental monitoring is with dual comb spectroscopy (DCS). DCS is attractive for its fast acquisition of high-resolution optical absorption spectra compared to common spectroscopic techniques.
The goal of this project is to realize a practical photonic integrated circuit (PIC) that can perform dual comb spectroscopy. This includes the creation of foundry compatible, chip scale OFCs that can be mass produced. Such PIC OFCs promises to dramatically reduce the cost and size of OFCs and to massively broaden the scope of OFC applications. For PIC OFCs, imec is pursuing multiple strategies for on-chip comb generation and DCS. These include mode-locked lasers, soliton generation in mirroring resonators, and electro-optic comb generation. Our main interests are in using them for sensors for monitoring of health and environment.The candidate will get a running start characterizing existing comb sources fabricated at imec. These can be further used to build a high performance DCS system. The candidate may also design new chip scale comb sources and DCS systems for fabrication in imec’s state of the art foundry. The candidate will be exposed to cross-department collaborations and may also collaborate with university partners. This challenging topic will require dedication to self-study and a critical and independent mindset.
