On the basis of the drive temperature, on the basis of the bias current setting part 232 and the driving temperature to set the bias current value of the temperature characteristics of the bias current value for the relevant drive temperature, so that the linear function having a slope other than zero, the temperature characteristics of the drive current value for the relevant driving temperature, and a driving current setting unit 233 for setting the drive current value so that the function having a slope other than zero. In addition, temperature characteristics and the temperature characteristics of the drive current of the bias current is a different function. Thereby, enabling the cost reduction, space saving, lower power of the semiconductor laser, and also in the driving of the semiconductor laser over the entire drive temperature range, good transmission characteristics and light output are obtained on the receiving side, the semiconductor laser drive device It can provide.
