Design Method of T-shaped Microstrip Electrode for Novel Polymer Modulator technical field The design method of the T-type microstrip electrode of the new polymer modulator, the waveguide of the modulator adopts the polymer material, and the electrode adopts the microstrip line structure, which can realize the speed matching of light and microwave, belongs to the field of optical communication technology, and involves Optical waveguide technology and microwave technology. Background technique Compared with LiNbO3 modulators, polymer materials can provide better phase velocity matching between microwave and optical carriers, so polymer electro-optic modulators can generally achieve high modulation bandwidth. The current optical network system with a single channel transmission rate of 10Gbps and 40Gbps has been realized. Although the current polymer modulator and even the LiNbO3 modulator can meet this communication requirement in terms of modulation bandwidth, the future ...

Problems solved by technology

Of course, as far as the polymer material itself is concerned, the degree of speed mismatch is not as large as that of LiNbO3, but if a more perfect speed match can be achieved through device design, then the bandwidth will definitely be greatly improved. can reduce the conductor loss, then the modulator bandwidth will reach a new height
