Abstract: A system for optical linear sampling and coherent detection of an optical signal OS comprises a source emitting a pulsed optical signal SP and an optical coupler that splits the pulsed optical signal SP into two replicas, the first replica of the pulsed optical signal SP is sent to a first optical hybrid circuit and the second replica of the pulsed optical signal SP is send to a second optical hybrid circuit, a source emitting an optical signal OS and optical coupler that splits the incoming optical signal OS into two replicas, the first replica of the incoming optical signal OS is sent to the first optical hybrid circuit and the second replica of the incoming optical signal OS is sent to a wavelength recovery device WVLR, whose output is a continuous-waveform optical signal CW at the central wavelength of the incoming optical signal OS, which sends it to the second optical hybrid circuit. such that the optical signal OS is sampled within the first hybrid circuit and the continuous waveform optical signal CW is sampled in the second hybrid circuit, and a device BDADC comprising balanced photodectors detecting optical signals at the output of the two optical hybrid circuits and an analog/digital converter ADC.

Abstract: A system for visualizing an optical signal OS through linear optical sampling, comprising at least one first subsystem relating to the processing of a pulse signal SP and at least one second subsystem related to the processing of an optical signal OS. The signals are broken down into two orthogonal polarization components, called vertical and horizontal. The pulse signal SP is broken down into vertical Vsp and horizontal Hsp components, and the magnetic TM and electric TE transverse propagation modes of the optical signal OS respectively give the vertical Vtm and Vte components and horizontal Htm and Hte components. The vertical and horizontal components are time-shifted. The vertical components and horizontal components of the pulse signal SP and optical signal OS are parallel. The successive, synchronized detection of vertical components and horizontal components makes it possible to sample the signal OS, which is visualized by electronic processing.
