Abstract:
A communication system includes an optical receiver that receives a modulated optical signal and converts same back to electrical form by a photodiode. The photodiode includes an optical input and a dc bias input, and outputs a photocurrent. The optical communication system includes a photodiode linear operation point feedback loop communicating with the photodiode based on an intermodulation distortion contour plot corresponding to the photodiode. The intermodulation distortion contour plot includes a plurality of linear operation points for the photodiode. The photodiode linear operation point feedback loop operates the photodiode at a respective operation point of the plurality of linear operation points. Optionally, the photodiode linear operation point feedback loop includes a voltage-biasing feedback loop receiving the photocurrent and outputting to the dc bias input a bias voltage based on the intermodulation distortion contour plot, and/or an optical power regulating feedback loop communicating with the optical input.

Claim (Index 6):
An apparatus comprising:\n an optical receiver comprising:\n a photodiode comprising an optical input and a dc bias input, and outputting a photocurrent; a regulated voltage source receiving a control signal and outputting a bias voltage to said dc bias input; and \n a feedback loop comprising:\n a spectrum analyzer receiving the photocurrent from said photodiode; \n a control unit communicating with said spectrum analyzer, said control unit being configured to access one of directly and indirectly an intermodulation distortion contour plot corresponding to said photodiode, the intermodulation distortion contour plot comprising a plurality of linear operation points for said photodiode; and \n a pseudonoise generator communicating with said control unit and said regulated voltage source and generating pseudo-noise, said pseudonoise generator outputting the control signal to the regulated voltage source, said regulated voltage source adjusting the bias voltage to said photodiode based on the pseudo-noise.
