Title: Equalizing circuit
Inventor: MATSUHASHI MASAMICHI
IPC: H04B10/2507
Filed: 1982-07-07
Abstract: PURPOSE:To compensate smoothly a ripple, etc. produced to the frequency characteristics, by branching a part of an input signal, inverting the output polarity of a delay circuit and synthesizing the inverted output with the input signal. CONSTITUTION:An input electric signal e2 is branched by a branching circuit 4 and reaches an inverting circuit 6 via a delay circuit 5. A signal of adverse polarity to the signal e2 of the output of the circuit 6 is added with the signal e2 at a synthesizing circuit 7 and turned into an output signal e3. If the delay time of the circuit 5 is set double as much as a transmission delay circuit for optical fiber transmission line, the signal e3 contains a component opposite to the ripples produced by reflection with the same frequency intervals as the ripples. Then the level is properly set for the delayed signal after synthesization, and therefore the deterioration can be reduced for the desired frequency characteristics. The delay time is set by a delay circuit 9 with tap, and the circuit 6 inverts the polarity through a transformer. The circuit 7 varies a variable attenuator 11 to set the quantity of a delay signal component contained in the signal e3.

Title: Semiconductor laser drive circuit
Inventor: FUKUTOME FUJITO
IPC: H01S5/042
Filed: 1988-05-18
Abstract: PURPOSE:To prevent an automatic optical power control (APC) device from feeding a surplus bias current at the rise time of a power source, by making a reference voltage fed through an APC reference voltage generating circuit lower than monitor voltage. CONSTITUTION:A laser drive circuit 1 outputs a laser drive pulse current Ip corresponding to an input pulse. As the laser drive pulse current Ip increases also with the upward tendency of voltage at the rise time of voltage, the outputted light level of a semiconductor laser 4 continues increasing from zero to a rated level until its level reaches rated voltage. During its starting time, a voltage rise control circuit 7 makes a reference voltage VSTD fed through an APC reference voltage generating circuit 2 lower than monitor voltage VBP and further, it is preferable that the reference voltage VSTD becomes zero. As an expression: (VSTD-VBP)<=0 is obtained in this way, a bias current IB does not flow. Thus, during the starting time, a surplus bias current is not fed to a semiconductor laser diode 4.
