  • Patent number: 12113145
    Abstract: An avalanche photodetector (APD) is proposed, wherein a photoconverter and at least one avalanche amplifier are located on the same wafer, its multiplication layer covers the entire surface of the conductive wafer, and its contact layer is formed in some region of the multiplication layer. Outside the contact layer, the multiplication layer functions as a photoconverter, thus facilitating the photocarriers getting into the avalanche amplifier. A dielectric-filled circular groove surrounding the avalanche amplifier suppresses photoelectric communication noises generated by neighboring avalanche amplifiers, thus allowing to manufacture multi-channel avalanche instruments with higher threshold sensitivity.
