Optical switch and optical disk drive |
摘要 |
Disclosed herein is an optical switch including: a dielectric substrate having a pair of main surfaces opposed to each other; and a pair of electrodes formed on the main surfaces of the dielectric substrate; wherein a direction of emergence of a light beam propagating in the dielectric substrate is controlled according to an electric field applied from the electrodes to the dielectric substrate; the dielectric substrate being formed with a periodic structure of polarization inverted domains each having a given shape; the light beam being incident on domain walls of the polarization inverted domains; the electrode formed on at least one of the main surfaces being separated into at least first and second electrodes in a direction of propagation of the light beam.
