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.

Optical waveguide and coupler devices and methods include a trench formed in a bulk semiconductor substrate, for example, a bulk silicon substrate. A bottom cladding layer is formed in the trench, and a core region is formed on the bottom cladding layer. A reflective element, such as a distributed Bragg reflector can be formed under the coupler device and/or the waveguide device. Because the optical devices are integrated in a bulk substrate, they can be readily integrated with other devices on a chip or die in accordance with silicon photonics technology. Specifically, for example, the optical devices can be integrated in a DRAM memory circuit chip die.
