We experimentally demonstrate optical signal processing in silicon ring resonators, including slow-light delay of digital and microwave photonic signals, dense wavelength conversions/multicasting, optical up-conversion, format conversions, temporal differentiation, and bio-sensing.
We propose a label-free biosensor based on concentric micro-ring resonators in silicon on insulator (SOI). The concentric micro-ring resonators offer another freedom to obtain deeper notches for higher detection sensitivity. The expanded modes also provide larger sensing area. A resonant frequency shift of ~1.37 nm is demonstrated, by numerical simulations, between the situation of using a single...
We propose an ultra-compact, label-free, parallel detection method by using an array of micro-ring resonators. Simulations of concentric micro-ring resonators with different parameters show that the device is suitable for such bio-sensing purpose.
