Patent ID: 8285153

Claim:
A monolithically integrated optical synthesizer for a light beam transmitting, comprising: an optical pulse shaper receiving the light beam and outputting a shaped beam being split by a splitter into a first and a second transmitting beams, the optical shaper improving a transmitting beam waveform quality by switching the synthesizer output on and off; the first and the second transmitting beams entering a first M-PSK modulator and a second M-PSK modulator producing a first and a second modulated output beams; a first and a second polarization controllers receiving the first and the second output modulated beams, respectively, and creating a third and a fourth beams having polarization state orthogonal to each other; a combiner that combines the third and the fourth beams forming a final output beam, wherein the pulse shaper is turning the synthesizer off during a data drive signals transitions, and wherein the pulse shaper, the first and the second M-PSK modulators, the first and the second polarization controllers and the combiner are formed as a part of a single planar chip of an electro- optical material.
