Abstract

A bending waveguide is provided including a core having an input end and an output end, wherein the output end has a near field enhanced aperture structure, and a metal cladding enclosing the core. The core is bent in a curve and a radius of curvature of the curve is a resonance radius at which an intensity of transmitted light with respect to a wavelength of incident light is a maximum. Thus, the direction of the incident light can be changed by a predetermined angle while maintaining the field enhancement characteristic of the conventional near field enhanced aperture without an additional optical element.
