More Information
Summary:An optical receiver including an ASIC, a light detector element, and a protective mask is disclosed. The light detector element is disposed on the ASIC and has a top surface oriented toward incident light, the top surface including a portion configured to receive the incident light and via which the incident light reaches an active area of the light detector element. The protective mask is placed over the ASIC so as to (i) cover, from the incident light, a portion of the ASIC, and (ii) provide an aperture that defines an optical path for the incident light through the protective mask to the portion of the top surface of the light detector element.
