Embodiment Construction
[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the public implementation manners of the present invention in detail with reference to the accompanying drawings.
[0046] refer to figure 1 , shows a schematic structural diagram of a polarization beam splitter based on a surface plasmon hybrid waveguide in an embodiment of the present invention. In this embodiment, the polarization beam splitter based on surface plasmon hybrid waveguide includes: a housing 100, and a first optical waveguide 200 and a second optical waveguide 300 arranged in the housing 100 .
[0047] Such as figure 1 , the first optical waveguide 200 and the second optical waveguide 300 are arranged in parallel, asymmetrically and at intervals. Wherein, the space between the first optical waveguide 200 and the second optical waveguide 300 forms a nano-slit 400 .
[0048] In this embodiment, the first optical wavegui...
