It can be used as optical waveguide gyro resonator, optical bandpass filter and other devices, and can also be used as a unit device to form components or systems together with other integrated optical devices. Therefore, it has broad application prospects in the fields of integrated optics and optical communication. Organic polymer materials are a new class of optoelectronic functional materials. Optical waveguides and devices made of polymer materials have important application potential and prospects in the field of optoelectronics. The selection range of the polymer material is wide, and the selection range of the corresponding refractive index is also large, and the refractive index can be adjusted by changing the monomer ratio. The electro-optic coefficient can be adjusted through molecular design, and has a large electro-optic coefficient and thermo-optic coefficient, so that the electro-optic effect and thermo-optic effect can be realized conveniently. In the preparation of waveguides, polymer materials can be spin-coated in large areas on substrates of any material, without high temperature treatment, and the preparation process is simple. Moreover, the cost of polymer materials is low, which has incomparable advantages especially for mass production. Using different substrates and polymer core and cladding materials can also obtain a larger birefringence index, so that the polarization-maintaining optical waveguide can be fabricated conveniently and the polarization characteristics of the device can be improved. Therefore, the organic polymer optical waveguide resonant ring is a promising integrated optical device. The thermal stability of organic polymer materials has always been one of the problems faced by organic polymer integrated optical devices. Compared with inorganic materials, organic polymer materials have a larger coefficient of thermal expansion and a more obvious change in refractive index with temperature.
由于光波导谐振环谐振的必要条件是光在环中行驶一周，其相位必须与原相位相差π的整数倍，因此，如使谐振环谐振，则对耦合器及谐振环的设计及制备要求非常苛刻。Since the necessary condition for the resonance of the optical waveguide resonant ring is that the light travels in the ring for a week, its phase must be an integer multiple of π from the original phase. Therefore, if the resonant ring is resonant, the design and preparation of the coupler and the resonant ring are very demanding. harsh.
