摘要： A semiconductor laser drive apparatus comprises a bias current setting section (232) which sets a bias current value on the basis of the drive temperature so that the temperature characteristic of the bias current value with respect to the drive temperature may be a linear function having a slope except zero and a drive current setting section (233) for setting the drive current value on the basis of the drive temperature so that the temperature characteristic of the drive current value with respect to the drive temperature may be a function having a slope except zero. The temperature characteristic of the bias current and that of the drive current are functions different from each other. With this, low cost, space-saving, and power-saving of a semiconductor laser are achieved, and a semiconductor laser drive apparatus enabling a good transmission characteristic on the reception side and a high optical output over the whole drive temperature range when driving the semiconductor laser can be provided.

摘要： A fixed voltage and a movable electrode are placed face to face with each other, and an insulating film is formed on the surface of the fixed electrode. The insulating film is made of a nitride film (SiN) as a main material, with oxide films (SiO2) being formed on the front and rear surfaces of the nitride film. Moreover, a plurality of protrusions are formed on an area facing the movable electrode of the upper face of the insulating film. The charge quantity in the insulating film is mainly determined by a film thickness of the oxide film, and the nitride film is used for maintaining a sufficient film thickness required for the voltage proof characteristic. Thereby, it is possible to suppress variations in operational voltage characteristics such as on-voltage and off-voltage in an electrostatic actuator so as to prevent phenomena in which the electrostatic actuator fails to turn on even when a rated voltage is applied to the electrostatic actuator and in which the electrostatic actuator fails to turn off even when the driving voltage is turned off.

When an input electrical signal having a predetermined frequency is detected, the input electrical signal having the predetermined frequency is converted to an optical signal and transmitted in the light transmission path. When input of an electrical signal other than the predetermined frequency is detected, the electrical signal other than the predetermined frequency is transmitted by the electrical transmission path without being converted to an optical signal due to the stop of the drive of the optical converter.
