| 英文摘要 | The present invention is notably directed to a photonic circuit device (100) for optical gain measurement, comprising: a substrate (10) with a photonic circuit, the latter comprising one or more waveguides (71, 72) defining two waveguide portions aligned along a same direction; an active gain section (62 – 66), on top of the substrate and coupled in the device for generating light by electrical pumping or optical pumping; at least two light couplers (75, 76) arranged such that at least a part of the active gain section is between the light couplers, and configured for coupling light between the active gain section and said waveguide portions; and a partial reflector (90) arranged so as to reflect light propagating along said same direction back to a center of the gain section, and wherein the device does not comprise any other reflector opposite to said partial reflector with respect to the active gain section and configured to reflect light back to the center of the gain section. The present invention is further directed to related gain measurement methods. |
