Abstract :
A low noise, high sensitivity resonant photodetector was realized using an interdigitated silicon photodiode and integrated oscillator circuitry. By placing the photodiode in a resonant loop and using an innovative transduction mechanism, an improvement in the noise performance of the device is observed. Specifically, an increase of 10% in signal to noise ratio is observed of the resonant device over the same device (photodiode) operated at DC.
