文摘
- •
A 4 bit ADC based on photonic crystal platform is presented.
- •
for the first time, successive approximation-like method is implemented to realize ADC in nonlinear photonic crystals.
- •
This tunable ADC uses Kerr-like nonlinearity as its tunable signal quantization mechanism.
- •
Our device use optical limiters inherently, thus it requires less nonlinear rings compared to their fiber based schemes.
- •
It consumes really low power with very low loss and it is ultra-compact sized compared to their fiber based schemes.
