Abstract
An optical deflector includes: a light transmitting portion through which a light passes; and a pair of electrodes arranged to oppose to each other with the light transmitting portion interposed therebetween. The light transmitting portion is a transparent ion conductor made of a single crystal or polycrystal. The pair of electrodes apply a predetermined voltage to the light transmitting portion to move ions inside the transparent ion conductor so as to change a traveling direction of the light passing through the light transmitting portion.
Claims3
An optical deflector comprising:
- a light transmitting portion through which a light passes;
- and
- a first electrode and a second electrode arranged to oppose to each other with the light transmitting portion interposed therebetween,
- wherein
- the light transmitting portion is a transparent ion conductor made of a single crystal or polycrystal,
- the first electrode and the second electrode apply a predetermined voltage to the light transmitting portion to move ions inside the transparent ion conductor so as to change a traveling direction of the light passing through the light transmitting portion, and
- the transparent ion conductor is a lithium ion conductor having a garnet-type crystal structure containing Li, La, and Zr.
