Abstract

An electro-optic clock recovery circuit comprising an electro-optic modulator circuit (605) operatively coupled to, a photodetector circuit (610), a buffer circuit (615) operatively coupled to the the photodetector circuit (610), a voltage controlled oscillator (620) operatively coupled to the buffer circuit (615) and to the electro-optic modulator circuit (605) wherein the electro-optic modulator circuit (605) receives and modulates a multi-channel input data stream (601), the photodetector circuit (610) responsive to the modulated input data stream (602) drives the voltage controlled oscillator in a phase locked loop through the buffer circuit (615), and the modulator circuit (605) is responsive to the voltage controlled oscillator (620) and is driven at a harmonic of the voltage controlled oscillator.
