OPTICAL COUPLING STRUCTURE AND OPTICAL COMMUNICATION DEVICE

Japanese Patent JP2018018046

A

PROBLEM TO BE SOLVED: To provide an optical coupling structure with a light-splitting section, and an optical communication device using the same.SOLUTION: An optical coupling structure and an optical communication device having the same are provided, the optical coupling structure comprising: a light input section 141 configured to receive an initial optical signal transmitted from an optical output unit 11 and convert the initial optical signal into a parallel light beam; a light splitting section 142 provided in a light path of the parallel light beam with a first and second reflective surfaces, slopes of which being either both positive or both negative, and configured to split the parallel light beam into a first portion and a second portion; a first light output section 143 provided in the light path of the first portion of the light beam and configured to convert the first portion of the light beam into a first optical signal to be transmitted to an optical transmission unit; and a second light output section 144 located in the light path of the second portion of the light beam and configured to convert the second portion of the light beam into a second optical signal to be transmitted to a photodetector.SELECTED DRAWING: Figure 1
