We demonstrate channel selective 0.1-Gb/s photoreceiver operation at telecom wavelength using a silicon high- Q photonic crystal nanocavity with a laterally integrated p-i-n diode. Due to the good crystal property of silicon the measured dark current is only 15 pA. The linear and nonlinear characteristics are investigated in detail, in which we found that the photocurrent is enhanced of more than 105 due to the ultrahigh- Q (Q≃ 105). With the help of two-photon absorption, which is visible at a surprisingly low input power of 10-8 W, the quantum efficiency of this device reaches ∼10%.
