ABSTRACT:
The fiber optic device in accordance with the present invention has a structure in which two fiber optic members are connected together, end faces thereof opposing each other. The input-side fiber optic member comprises cores extending in a predetermined direction and a light absorber surrounding the cores. The output-side fiber optic member comprises cores extending in a predetermined direction, and a cladding surrounding the cores. The input end face of the input-side member is inclined with respect to core axes therein. In this device, the angle of inclination of the input end face of the input-side member or the angle formed between the output end face of the output-side member and each core axis in the output-side member can be set to a value relatively near to 90.degree.. Accordingly, this device can be attached to a photodetector with relative ease. Also, a light receiving member formed by this attachment is relatively compact.
