Our expertise allows us to couple fibers or fiber arrays to Photonic Integrated Circuits (PICs). This service ensures efficient and reliable optical communication between the fibers and the PICs, optimizing the performance and functionality of the integrated system. For single fiber alignment two side optical coupling is necessary (input east coast and output west coast). For fiber array coupling, alignment channels on the chip are required. We provide the full value chain of optical and mechanical simulations, packaging, and characterization of coupling efficiency with insertion loss measurements using power and OBR measurements.
