PROBLEM TO BE SOLVED: To provide components for transmitting optical data in which high sensitivity and high transmission output can be attained through small dimensions. SOLUTION: An emitter chip 10 transmitting an infrared beam, a detector 8 receiving the infrared beam and an optical system 2 having an optical axis for focusing a beam to be transmitted and received are arranged, as components, in a housing comprising one section or many sections. In such an arrangement for transmitting a directional bilateral optical data, transmission output and receiving sensitivity are enhanced because a reflector 13 is disposed concentrically to the optical axis around the components 8, 10 and the optical system 2. |
