摘要：An optical switch for switching signal light by allowing the signal light toobliquely enter a non-linear optical thin film containing nano-crystal of metal oxide froma light path disposed in an optical material, and irradiating visible excitation light to thenon-linear optical thin film to induce a total reflection phenomenon, thereby controllingthe reflection and transmission behavior of the signal light, wherein a difference betweena temperature coefficient factor of an optical index of the non-linear optical thin film andthat of an optical index of the optical material which is in contact with the non-linearoptical thin film is determined to be 15×10/° C. or below. Preferably, it is determined tobe zero or substantially zero. Thus, an influence due to the temperature increase iscancelled, and a malfunction of switching can be avoided.
