| 英文摘要 | A bidirectional signal transmission device using light which adopts a photodiode-incorporated vertical cavity surface emitting laser (VCSEL) as light devices so that signal transmission and reception between facing light devices is achieved via the same channel, is provided. This bidirectional signal transmission device using light includes an optical unit (30), a first circuit unit for controlling a first light device (31), and a second circuit unit for controlling a second light device (37). The optical unit includes first and second light devices (31, 37) having a VCSEL part and a photodiode part incorporated with the VCSEL part, at least one optical fiber (35) installed between the first and second light devices (31, 37), and diffraction elements (34, 36) installed between the first light device (31) and the input port (35a) of the optical fiber and between the second light device (37) and the output port (35b) of the optical fiber (35), respectively, for selectively diffracting incident light so that light output from the optical fiber is received by the photodiode part. In this bidirectional signal transmission device using light, light emitted from an optical fiber is diffracted in an +1-th and/or -1-th order by diffraction elements, and heads for the photodiode part of the light devices, so that a received signal having a high S/N ratio can be detected. Also, the bidirectional signal transmission device using light adopts a photodiode-incorporated VCSEL manufactured as a single body in a semiconductor manufacturing process, so that a die-bonding process can be omitted. |
