Abstract
PURPOSE:To enable the conversion of multiple wavelength light signals to be transmitted independently into an electric signal via one element by planarly integrating a plurality of photoelectric converters for converting the light signals of different wavelengths selectively into electric signals. CONSTITUTION:Three photoelectric converters 1, 2, 3 are aligned on an N<+> type InP substrate and are made of InGaAs compound semiconductor. The light absorption layers 13, 14, 15 respectively absorb the lights of wavelengths lambda1, lambda2, lambda3 for the multiple wavelength input lights lambda1, lambda2, lambda3. The photoelectric converter elements are insulated and isolated via a proton illumination high resistance layer 18. Reverse bias voltage is applied to the P-N junction of the photoreceptor via electrodes 31, 32, the input light of the respective wavelength can be converted into electric signals as the variations in the output voltages V1, V2, V3 upon projection of the lights. In this manner, the light signals of the multiple wavelength can be independently converted into electric signals via one element, thereby simplifying the configuration of the converter and reducing the size of the converter.
