Abstract: PROBLEM TO BE SOLVED: To provide an optical switch which can decrease insertion loss and cross talk. SOLUTION: The optical switch operates in such a manner that at least a pair of opposing optical waveguides is intersected with each other and the optical paths of light beams are switched by inserting and retracting a reflector into and from the intersection of the optical waveguides. In the state where the reflector is inserted into the intersection, the reflector is in a size larger than an ellipse having the diameter twice or more of the diameter of the light beam on the reflector with respect to the center of the light beam as the reference. Or, in the state where the reflector is retracted from the intersection, the reflector does not overlap the ellipse having the diameter twice the diameter of the light beam with respect to the center of the light beam as the reference.

Abstract: PURPOSE:To prevent the breaking of an electrostatic induction thyristor due to the steep increase of current. CONSTITUTION:The anode currents of an electrostatic induction thyristor 9 are increased suddenly when an on signal is output from a gate driving-signal source 1, and a MOSFET 6 is turned on when the product L (dIA/dt) of the inductance L of an inductor 10 and the rate of time change (dIA/dt) of anode currents IA, is made larger than the threshold value Vth of the MOSFET 6. Consequently, currents fed from a DC power supply 2 to the electrostatic induction thyristor 9 are made to flow through the MOSFET 6. Turn-off currents are extracted from the gate of the electrostatic induction thyristor 9 by a capacitor 7 being charged for an on period at the same time, and the electrostatic induction thyristor 9 is brought to an off state, thus protecting the thyristor 9.
