ABSTRACT:
An optical guide43is partly buried in a lens43on the diameter of its aperture, the lens43converging received light incident from the end face of an optical fiber onto a light receiving element15and the optical conductor33having a refractive index larger than that of the lens43. The optical guide33is composed of a buried portion33-1and an extending portion33-2, and transmitting light22incident on the optical guide33from the end face33cof the extending portion33-2is reflected by a reflecting surface33aand launched into the optical fiber. The transmitting light22is guided by the optical guide33to the end face of the optical fiber without leakage to the receiving-side portion.
