Abstract
The present invention is in related to a miniature surface plasmon resonance waveguide device with sinusoidal curvature compensation and at least comprises: a substract, a waveguide structure, a sensing film layer and a cover layer, wherein the waveguide structure is configured with the function of sinusoidal curvature compensation and installed above the substract, further that, the waveguide structure includes a light input port and a light output port; the sensing film layer is on a special region of the waveguide structure, the special region is a sensing region; the cover layer is upper than the substract and has an opening. By means of the optimal curve figure of the sinusoidal curvature compensation, attenuation of light energy can be minimized while in propagation, and allows the input and output of the light on the same side of the device.
