Abstract :
1.5 μm two-photon absorption in a single photon counting silicon avalanche photodiode at record continuous-wave levels below 100 μW is reported. Autocorrelation of a 10 GHz, 1.67 picosecond pulse-train using this device demonstrates 1.5 × 10-3 (mW)2 peak-power times average-power sensitivity without the use of lock-in detection
