An object of the invention is to provide a control apparatus and control method for an optical switch with a three-dimensional structure using MEMS mirrors, that can accurately compensate for a change in characteristic due to a temperature variation from an initial setting time, to perform the high speed switching of optical paths. To this end, the control apparatus of the invention, stores in advance in an initial value memory, information of reference temperature related to an inclination angle of each of the MEMS mirrors corresponding to set optical paths, and when a switching command of the optical paths is received, accesses the initial value memory to acquire the information related to the inclination angle at the reference temperature, and also accesses a temperature sensor to read out a temperature of the optical switch, and based on the information acquired from the initial value storing section and the temperature read out from the temperature detecting section, calculates a drive voltage in which a deviation due to the temperature variation from the reference temperature is compensated for, and gives this to the corresponding MEMS mirror as an initial value of the drive voltage.
