Abstract (en)

[origin: WO2022112679A1] The invention relates to a photonic chip (10) comprising at least one photonic circuit (1) including at least one laser source (L) for supplying a first radiation, referred to as local oscillator (LO), to an optical mixer (M) and for supplying an emission radiation (Re) to a coupling device (C), the local oscillator (LO) and the emission radiation (Re) having a predetermined polarisation. The coupling device (C) is configured to propagate in free space, from a measuring surface (Sm), the emission radiation (Re) in the form of an emission light beam, to receive, in return, on the measuring surface (Sm) a reflected light beam and to guide it towards the optical mixer (M) as reflected radiation (Rr) having the predetermined polarisation. The optical mixer (M) generates a measurement signal (V) by interferometric pulse of the local oscillator (LO) and the reflected radiation (Rr). The invention also relates to an optical component including such a photonic chip.
