Abstract
Photo-resonator optical detectors and optical receiver systems incorporating same, In one example, an optically resonant detector includes a housing having an optical window, a photodetector disposed within the housing, and an optical resonator disposed in optical alignment with the photodetector within the housing and positioned between the optical window and the photodetector, the optical resonator being configured to receive an input optical signal via the optical window and to provide an output optical signal to the photodetector.
Claims20
An optically resonant detector comprising:
- a housing having an optical window;
- a photodetector disposed within the housing;
- and
- an optical resonator disposed in optical alignment with the photodetector within the housing and positioned between the optical window and the photodetector, the optical resonator being configured to receive an input optical signal via the optical window and to provide an output optical signal to the photodetector.
An optical receiver comprising:
- a photo-resonant detector including an integrally formed and optically aligned combination of a photodetector and an optical resonator, the photo-resonant detector being configured to receive an input optical signal and to provide an electrical signal based on the input optical signal, an amplitude modulation of the electrical signal being representative of a modulation of the input optical signal;
- an analog to digital converter configured to receive the electrical signal from the photo-resonant detector and convert the electrical signal into a digital signal;
- and
- a digital processing subsystem configured to receive and process the digital signal.
An optical receiver comprising:
- a photo-resonant detector including a housing having an optical window, a photodetector disposed within the housing, and an optical resonator disposed in optical alignment with the photodetector within the housing and positioned between the optical window and the photodetector, the optical resonator being configured to receive an input optical signal via the optical window and to provide an output optical signal to the photodetector, the photodetector being configured to convert the output optical signal into an electrical signal;
- an analog to digital converter configured to receive the electrical signal from the photo-resonant detector and convert the electrical signal into a digital signal;
- and
- a digital processing subsystem configured to receive and process the digital signal.
