OPTICAL SIGNAL SELECTION DEVICE AND CONTROL METHOD OF OPTICAL SIGNAL SELECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress the number of control parameters from increasing in comparison with increase in the number of combinations of routes.SOLUTION: An optical signal selection device comprises: an optical deflector that has an input/output fiber optic array having a plurality of fiber optics arrayed along a prescribed switch direction, and an optical deflection element arrayed with respect to a direction almost vertical to the switch direction, and causes each of the optical deflection elements to deflect an incident optical signal at a controllable angle with respect to the switch direction and to reflect the deflected optical signal, and thereby couples a route of the optical signal between the first and second fiber optics; a converging optical system that causes mutually parallel optical signals incident from each fiber optic to be converged onto an element surface of the optical deflector; a computation unit that computes one argument for referring to a control parameter about the angle from a combination of the first and second fiber optics; a storage unit that stores the control parameter so as to allow the control parameter to be referred to on the basis of the one argument; and a drive unit that drives the optical deflection element on the basis of the control parameter referred to based on the one argument.SELECTED DRAWING: Figure 1
