Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings. Usually, the communication window in an optical communication system is near-infrared light. Here, it is assumed that the working wavelength of the optical signal is 1.55 μm. Such as figure 1 As shown, the waveguide core material 5 is polysulfone doped with ICP-E, and its refractive index is 1.67; the lower cladding material 4 is polymer material UV158, and its refractive index is 1.50; the upper cladding material 6 is polymer material PMMA , whose refractive index is 1.48; the upper cladding material 7 is liquid crystal E7, whose refractive indices corresponding to ordinary light and extraordinary light are 1.50 and 1.685, respectively. Its waveguide core thickness , ridge height and width They are 1.0 μm, 0.8 μm, and 5.0 μm, respectively.
[0021] Here, the beam propagation method (BPM) is used to simulate the optical performance of the waveguide adjustable pol...
