Abstract:
An optical device includes a clad composed of a material having a first refractive index, a core which is embedded in the clad, composed of a material having a second refractive index different from the first refractive index, and tapers toward the end-point thereof, and a light-transmitting layer which is composed of a material different from the material having the second refractive index and cuts across an optical path at the end-point thereof.
