Optical measurement apparatus

An optical measurement apparatus configured to measure a photonic integrated circuit (photonic IC), the optical measurement apparatus comprising:

• a substrate;
• at least one optical waveguide device disposed on the substrate;
• and
• a first connector and a second connector which are connected to the at least one optical waveguide device, wherein the at least one optical waveguide device comprises an optical waveguide extended to the second connector from the first connector, a part of an optical signal from a first optical fiber is sequentially transmitted to the at least one optical waveguide device through the first connector;
• transmitted to an inside of the photonic IC through at least one first evanescent coupler of the photonic IC, transmitted to the at least one optical waveguide device through at least one second evanescent coupler of the photonic IC, and transmitted to at least one second optical fiber through the second connector.
