Abstract:
An opto-electronic oscillator ( 10 ) comprising: an optical source ( 12 ) to generate an optical carrier signal having a carrier wavelength; an optical phase modulator ( 14 ) to apply a sinusoidal phase modulation to the optical carrier signal to generate two first order sidebands having a π phase difference between them; an optical phase shifter ( 16 ) comprising an optical resonator configured to apply a substantially π phase-shift to one of the first order sidebands at a preselected wavelength within an optical spectrum of said first order sideband; and a photodetector ( 18 ) configured to perform optical heterodyne detection of the optical carrier signal with both: said one of the first order sidebands substantially it phase shifted by the optical resonator; and the other of the first order sidebands, to generate an electrical carrier signal ( 20 ), and wherein a first part of the electrical carrier signal ( 20 a ) is delivered to an electrical output ( 22 ) and a second part of the electrical carrier signal ( 20 b ) is delivered to the optical phase modulator as a drive signal.

Claim (Index 6):
An opto-electronic oscillator as claimed in  claim 4 , wherein the optical ring resonator is configured as an add-drop filter comprising an input port to receive the optical carrier signal and the two first order sidebands from the phase modulator, a drop port to output said one of the first order sidebands following application of the substantially\n \u03c0 phase-shift and a throughput port to output the optical carrier signal, wavelengths other than the preselected wavelength within the optical spectrum of said one of the first order sidebands and the other first order sideband, and wherein the phase shifter comprises a first optical path from the throughput port to the photodetector and a second optical path coupling the drop port to the first optical path.
