Title: Variable optical attenuator
Inventor: AKAZAWA MASAYOSHI
IPC: G02F1/015
Filed: 2010-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a variable optical attenuator more compactible.SOLUTION: A variable optical attenuator includes at least a substrate 101 and an optical penetration part 102 composed of a crystal of vanadium oxide. An optical waveguide is configured with the optical penetration part 102 used as a core and the substrate 101 used as a clad layer. In the optical penetration part 102 composed of a crystal of vanadium oxide (VO), two states of insulator phase and metal phase replace each other by photoinduced phase transition, and an optical-absorption characteristic changes. Therefore, the variable optical attenuator can switch between the two states at the optical penetration part 102 through the photoinduced phase transition by incident light, and can switch an attenuating state of light penetrating (guided). For example, when the light with intensity causing the photoinduced phase transition enters, the optical absorption increases due to phase transition of the optical penetration part 102 into the metal phase, and the intensity of light entering and penetrating is attenuated.
