Lab-on-a-Chip Biophotonic Sensor Platform: Frequency separated multiplexed optical biosensing

Photonic crystal resonators offer narrow spectral resonances, simple interpretation of the output signal and compatability with the silicon-on-insulator (SOI) platform, leading to cheap and mass-producible sensors. The small size of photonic crystal resonators pave way for a high sensor density on any given chip. We have designed and simulated a highly compact single-input single-output biosensor capable of simultaneously detecting four analytes at once.
