Abstract:
1. An optical path switching device comprising a light transmitting portion where a plurality of refraction regions are formed so that the refractive index of light can be controlled uniformly in a direction perpendicular to a direction in which light propagates by using an electro-optic effect, the thickness of the light transmitting portion varying along the direction in which light propagates, a first electrode layer and a second electrode layer which are formed so as to sandwich the light transmitting portion and cover at least the portions of the refractive regions, a first support portion which is placed so as to make close contact with the first electrode layer via a first adhesive layer on a side that does not make contact with the light transmitting portion, and a second support portion which is placed so as to make close contact with the second electrode layer via a second adhesive layer on a side that does not make contact with the light transmitting portion.
