Abstract:
Optical biosensors based on silicon hold great promise as low-cost, lab-on-chip sensor array elements due to their compatibility with both standard microelectronics processing and standard surface functionalization techniques. The sensitivity of these optical biosensors is fundamentally derived from the level of interaction between light and the target molecules to be detected. This talk will discuss approaches to increasing light-matter interaction of silicon photonic biosensors. In particular, several biosensor designs, including photonic crystals, ring resonators, and Bloch surface wave structures, and a method of in-situ bioreceptor synthesis will be described, along with illustrative examples of specific molecular detection using silicon photonic components.
