Patent ID: 7697579

Claim:
A coupled optoelectronic oscillator having optical frequency stabilization comprising: a harmonically mode-locked laser cavity having a Mach-Zehnder modulator for mode-locking and one single intracavity Fabry-Perot etalon to allow only one single supermode to lase, generating a coupled optoelectronic oscillator signal; a stabilization loop coupled with the one single intracavity Fabry-Perot etalon to detect changes in the laser cavity optical frequency and generate an error signal, conditioning the error signal by a proportional gain-integration-differentiation controller and feeding the conditioned error signal to a piezoelectric actuator to compensate for the detected frequency change in the optical frequency to achieve supermode suppression and stabilize the mode-locking of the laser frequency stabilization with the one single intracavity Fabry-Perot etalon; and an electrical loop between the laser cavity and the stabilization loop for driving the Mach-Zehnder modulator with the coupled optoelectronic oscillator signal for the coupled optoelectronic oscillator to be optical frequency stabilized while remaining self contained.
