Abstract

An embodiment of the invention relates to an optical signal generator comprising an optical emitter configured to generate a beam of optical radiation, a first and second beam deflecting element, a modulator being located between the beam deflecting elements, a phase shifter located between the beam deflecting elements, a control unit configured to control the phase-shift of the phase shifter, wherein the first and second beam deflecting elements, the phase shifter and the modulator are located in the same plane, wherein the beam generated by the optical emitter is angled relative to said plane, wherein said first beam deflecting element is configured to deflect the emitter's beam into the plane towards the modulator, said modulator being configured to modulate the emitter's radiation and outputting a modulated radiation, wherein said second beam deflecting element is configured to deflect the modulated radiation off the plane towards an output port of the signal generator, wherein the modulator is configured to modulate the emitter's radiation in response to an electrical data signal that is applied to the modulator and comprises a data stream, and wherein the control unit is conf…
