Silicon nanophotonic devices for integrated lab-on-a-chip sensing.

We present our recent progress in designing nanophotonic devices for integrated sensing applications. We focus on Si-based microresonators and on-chip spectrometers as the main building blocks to implement compact sensing platforms with strong light-matter interaction. The performance of these devices is discussed, and their future prospects in realizing low-power low-cost portable multi-purpose sensing systems are addressed.
