Title: Two-way transmission system
Inventor: SUZUKI YASUHIRO
IPC: H04B10/60
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To allow the system to modulate a DC light which is transmitted from a center equipment and to loop back it, while receiving a modulated light and compensating a transmission loss by making a semiconductor crystal function as an absorbing layer or an optical amplifier layer, based on the switching of a bias voltage. SOLUTION: A reverse bias is applied to an active layer 21 of a semiconductor optical amplifier, in the case of receiving a modulated outgoing signal light to be made to function as a waveguide photodetector. A forward bias is applied to the active layer 21 of the semiconductor optical amplifier in the case of receiving a DC outgoing signal light to be made to function as a photoamplifier. The gain of the photoamplifier is changed by using a transmission signal from a user equipment to the center equipment to modulate the forward current, so as to apply intensity modulation to the DC light. The modulated light is reflected in a high reflection film 27 at a rear end face and sent as an incoming signal light to the center equipment.  Since the semiconductor photoamplifier modulates the DC light with a wavelength sent from the center equipment and sends the modulated light back to the center equipment, there is no nud on the user equipment side for controlling the wavelength.
