Abstract
An optical element includes a waveguide and a deflector. The waveguide propagates light incident at a predetermined angle while reflecting the light between the first plane and the second plane. The deflector is formed as a plate having a third plane being opposed to the first plane in the deflector, the first plane and the third plane are spaced apart from each other at a distance smaller than a propagation distance capable of propagating an evanescent wave of first light. The deflector has a plurality of reflecting surfaces arranged on the rear side of the third plane. The reflecting surfaces reflect the first light that has been incident on the first plane to be propagated as an evanescent wave, into a direction substantially perpendicular to the first plane. A medium interposed between the first plane and the third plane has a refractive index lower than that of the waveguide.
