摘要： An integrated optical head is provided. In the integrated optical head, a light source emits light. A waveguide guides the light. An input coupler is located at one edge of the waveguide, and couples light emitted from the light source and transmits the coupled light to the waveguide. An output coupler is located at another edge of the waveguide, and couples light emitted from the waveguide and focuses the coupled light on an optical disc. A light path changing unit is installed on the waveguide, and changes the light path of light that has been reflected by the optical disc and then passed through the output coupler. An optical detector receives the light passed through the light path changing unit and converts the received light into an electrical signal in order to detect information from the optical disc. Accordingly, an input coupling efficiency and an output coupling efficiency are improved, such that light loss is reduced. Thus, recording and reproduction of an optical head can be improved, and a light, compact, integrated optical head can be obtained.

摘要： 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.
