| titleOfInvention | Straight waveguide phase modulator, integrated assembly and preparation method |
| abstract | The invention discloses a straight waveguide phase modulator, an integrated component and a preparation method, wherein lithium tantalate crystals with smaller birefringence effect are used as substrate crystals of the straight waveguide phase modulator, the optical path difference of orthogonal polarized light waves is smaller, and the transmission loss and the coupling loss related to polarization are lower. In addition, the Y-branch waveguide coupler with the functions of the polarizer and the coupler and the straight waveguide phase modulator are integrated on the same lithium tantalate wafer. The optical fiber current transformer system based on the integrated assembly has the advantages of higher reliability, lower assembly complexity and lower manufacturing cost. |
