| Abstract(in English) | Ultrasmall InGaAs photodetectors based on a photonic crystal waveguide with a buried heterostructure (BH) were demonstrated. A high DC responsivity of ～1A/W was achieved for the 1.7-μm-long detector. The dynamic response revealed a 3-dB bandwidth of 30GHz and a 40-Gb/s NRZ eye pattern. These results were thanks to the strong confinement of both photons and carriers in a small BH region and will pave the way for unprecedented nano-photodetectors with a high quantum efficiency, high speed and small capacitance. Our device may enable us to eliminate electrical amplifiers for future optical receivers and subsequent ultralow-power optical links on a chip. |
