The optical heterodyne synthesizer includes first and second phase-locked lasers, where the first laser feeds the multi-tone optical comb generator and the second laser is a single tone laser whose output light provides a frequency translation reference. At least one photodetector is provided for heterodyning the frequency translation reference with the optical output of the photonic oscillator to generate a spread spectrum waveform. A receiver pre-processor may be provided to operate on the spread spectrum waveform.

Abstract: A frequency synthesizer for generating a multiple tone lightwave signal that can be converted into an RF carrier or local oscillator signal. The frequency synthesizer comprises a multiple mode master laser, two slave lasers injection-locked to the master laser, an optical coupler coupling the optical outputs of the two slave lasers, which produces an optical heterodyne output. The frequency synthesizer further comprises a homodyne phase-lock loop providing feedback control over one of the slave lasers and a heterodyne phase-lock loop providing feedback control over the other slave laser. A local oscillator selector is used to select the optical mode to which one of the slave lasers is locked, thus providing selection of the frequencies of the heterodyne output.

Abstract: A low voltage optical phase modulator includes a splitter having an input, a first output, and a second output. The input receives an optical signal and is split between the first and second outputs. A phase adjustment element is coupled to the second output and produces a predetermined optical shift in the optical signal to produce a phase-shifted optical signal. A first electroabsorptive element is coupled to the first output and blocks transmission of the optical signal when the first electroabsorptive element is activated with a low voltage. A second electroabsorptive element is coupled to the phase adjustment element and blocks transmission of the phase-shifted optical signal when the second electroabsorptive element is activated using the low voltage. An optical combiner having a first combiner input, a second combiner input, and a combiner output is coupled to the first and second electroabsorptive elements and receives the optical signal and the phase-shifted optical signal. The combiner combines these optical signals to produce a binary encoded optical signal. The present invention thus achieves an improved low voltage optical phase modulator. The present invention is advantageous in that substantially larger than 180 degrees phase shift can be achieved with the same low voltage by using optical paths having longer lengths.
