An optical receiver may include a photodetector and a differential amplifier. The photodetector is coupled to an optical waveguide. The optical waveguide is configured to provide an optical signal encoding data. A first terminal of the differential amplifier is coupled to receive a photodetection signal from the photodetector. A second terminal of the differential amplifier is coupled to receive, from a noise measurement unit, a reference signal representing a noise component of the photodetection signal. The differential amplifier is configured to provide an amplifier signal encoding at least some of the data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Devices and techniques for integrated optical data communication","description":"Devices and techniques for integrated optical data communication.
