Abstract
Silicon photonics is best known for its application in optical interconnect, optical datacom and telecom, where it is rapidly moving into industrial deployment. But the key asset of this technology – ultra-compact and powerful photonic functionalities made in a CMOS-fab – may be game-changing for many photonics applications with a reasonable volume or a cost-critical market. This is particularly true for lab-on-chip applications where the chip is a consumable and also in point-of-care medical applications where affordability and portability of an instrument is very important.
In this talk I will discuss a number of examples from exploratory research in recent years that build on a generic silicon photonics technology platform to develop devices for biomedical applications. This includes biosensors, gas sensors for breath analysis, laser Doppler vibrometry for blood pulse velocity measurement, optical coherence tomography, continuous glucose monitoring, Raman spectroscopy on chip etc. I will also discuss the potential of nonlinear optics in silicon to implement special functions that may aid biological sensing, such as supercontinuum generation, parametric amplification and stimulated Raman scattering.
