Patent ID: 7889993

Claim:
An optical transceiver module comprising: a light source configured to receive a modulation signal and to produce an optical data signal based on the received modulation signal; a light source driver configured to produce the modulation signal based on an electrical data signal received by the light source driver; a reflector, the reflector receiving light corresponding to the optical data signal produced by the light source, the reflector including a mirroring surface and a diffraction-inducing structure, wherein the diffraction-inducing structure is formed on or in the mirroring surface, the mirroring surface reflecting at least a portion of the received light in a first direction, the diffraction-inducing structure diffracting at least a portion of the received light in at least a second direction, the second direction being different from the first direction; and at least a first detector, the first detector receiving at least a portion of the light diffracted in the second direction and converting the received diffracted light into electrical energy.
