ABSTRACT:
An optical transmitting/receiving module including a light emitting element, a light receiving element, a transmitting optical communication line for transmitting an optical signal, a receiving optical communication line for receiving an optical signal, and a single aspherical lens for coupling the transmitting light emitted from the light emitting element to the transmitting optical communication line and for coupling the receiving light emergent from the receiving optical communication line to the light receiving element. The light emitting element is arranged so that the center line of a beam of the transmitting light emitted from the light emitting element is inclined with respect to the optical axis of the lens. With this arrangement, the optical transmitting/receiving module can be reduced in size.
