[0036] In order to make a detailed description thereof in conjunction with the
[0037] like figure 1 As shown, the present invention provides a low loss integrated bending photovoltaic design method, that is, a shape optimization method of a curved light waveguide, which is optimized to optimize the boundary curve of the curved light waveguide, and minimize waveguide loss. The curved optical waveguide refers to a light waveguide that is curved on the plane, and the common curved photographing is a circular curved light waveguide, but the insertion loss can be further reduced by optimizing its shape in the present invention.
[0038] The steps of the low-loss integrated bending optical waveguide design method are as follows:
[0039] S1, obtain the effective bending radius of the curved light waveguide to be designed, the waveguide cross-sectional size, material parameters, transmission wavelength, and cladding structure parameters, and use the third-order beezeel function...
