Optical Power Monitoring with Ultrahigh Sensitivity in Silicon Waveguides and Ring Resonators
We demonstrate optical power monitoring using a silicon resistor enabled by the surface and defect states-induced photoconductance effect. Ultrahigh optical power detection sensitivity of −40 dBm under a low AC drive voltage of 5 mV is obtained with the facilitation of a lock-in amplifier...
