IPC: H04B10/2507
Filed: 2013-02-26
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmitter which prevents continuous occurrence of signal error caused by an intensity or a polarization state of return light from an external reflection point.SOLUTION: Optical output from a DFB-LD (Distributed-Feedback Laser Diode) 101 is demultiplexed, and the demultiplexed light is received by a photodiode 111 to output a voltage, a part of the light-reception voltage is detected at fixed time intervals by a sample/hold circuit 112 and detected again by shifting a sample point a little. On the basis of a detection voltage of the sample/hold circuit 112, an FPGA (Field Programmable Gate Array) 115 creates a histogram of the light-reception voltage, observes an optical output detection frequency in a predetermined optical output intensity interval in the created histogram and generates an output voltage amplitude Vf. A deviation between the output voltage amplitude Vf and a GND potential Vr which is a target value is operated by a PID (Proportional-Integral-Derivative) controller 118, and a signal correlated to the deviation is outputted to a control waveguide drive circuit 119. The control waveguide drive circuit 119 outputs a voltage Vcnt to be applied to a control waveguide 102 on the basis of an output signal of the PID controller 118.
