Title: Optical transmitter-receiver
Inventor: KOBAYASHI TAKESHI
IPC: H04B10/50
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To enable bilateral simultaneous transmission and prevent deterioration of transmission efficiency, by introducing an optical signal outputted from a light emitting element to an optical fiber installed outside a package through a lens system, and receiving the optical signal from the optical fiber with a light receiving element arranged outside the light emitting element. SOLUTION: In the case of transmission, an optical signal L1 outputted from a light emitting diode 3 is converged by a spherical lens 2 and is made incident on an optical fiber 1. At this time, an optical transmitter-receiver is aligned in the surface perpendicular to its optical axis, in such a manner that the maximum optical output is coupled with the optical fiber 1. In the case of receiving, an optical signal L2 spreading around the spherical lens 2 out of the optical signals outputted from the optical fiber 1 is received by a photodiode 4. Consequently, one optical element is not commonly used in a light emitting mode and a light receiving mode, and a long switching time in the case of changeover from the light emitting mode to the light receiving mode is made unnecessary.
