Abstract :
The combination of Si-based ultra-high Q micro-resonators and ultra-compact photonic crystal on-chip spectrometers has enabled highly-sensitive lab-on-a-chip sensing structures with orders-of-magnitude smaller size compared to conventional bulk sensing systems. Details of the design along with their experimental demonstrations will be presented.
