摘要：
A light switching apparatus includes an optically non-linear etalon, a first optical part for applying a signal light of a linear polarization to the optically non-linear etalon, and a second optical part for applying a control light of a circular polarization or elliptical polarization to the optically non-linear etalon. The control light varies a refractive index of an optically non-linear substance of the optically non-linear etalon to thereby perform a switching operation on the signal light.
