摘要： An integrated photonic device comprises: an input waveguide configured to extend in an input plane, and an output waveguide configured to extend in an output plane, wherein the output plane is parallel to or contained within the input plane; an input coupler optically coupled to the input waveguide, wherein the input coupler is configured to redirect a light signal out of the input waveguide and the input plane; a light property modifier configured to receive the light signal from the input coupler and reflect the light signal towards the output plane, wherein the light property modifier is configured to selectively adjust an optical path length of the light signal; and an output coupler optically coupled to the output waveguide, wherein the output coupler is configured to receive the reflected light signal from the light property modifier and redirect the light signal into the output waveguide and the output plane.

摘要： A phase difference measurement device comprises at least two optical waveguides arranged in parallel in a first plane. Each optical waveguide comprises a proximal portion and a distal portion. The proximal portion of at least one of the optical waveguides comprises a phase-shifting device configured to induce a phase shift of a light wave being transmitted in the phase difference measurement device. The device further comprises at least one phase interrogator device arranged in the first plane between two neighboring optical waveguides of the optical waveguides. The phase interrogator device is configured to couple light from the two neighboring optical waveguides to interfere in the phase interrogator to generate an interference light wave. At least one photodetector is arranged for detecting the interference light wave. The photodetector is arranged in a second plane other than the first plane.
