Abstract:
1. A miniature surface plasmon resonance device with sinusoidal curvature compensation, comprising: a substrate; an waveguide structure, said structure having sinusoidal curvature compensation, resting on top of said substrate, and having a light input port and a light output port; a sensing film layer, standing at a specific area on top of said waveguide structure, where the specific area is a sensing area; and a cover layer, covering said waveguide device and having a hole at said sensing area; based on said waveguide structure having sinusoidal curvature for compensation, a light beam guided into said light input port of said waveguide structure, propagating along a path with said sinusoidal curvature for compensation, passing across said sensing area, and emitting from said light output port of waveguide structure.
