Rof Electro-optic modulator LiNbO3 MIOC Series Y-Waveguide Modulator

Short Description:

The R-MIOC Series Y-Waveguide Modulator is a LiNbO3 multifunctional integrated optical circuit (LiNbO3 MIOC) based on microelectronic technology, which can achieve polarizer and analyzer, beam splitting and combining, phase modulation and other function. The waveguides and electrodes are fabricated on LiNbO3 chip, the output and input fibers are precisely coupled with the waveguides, then the whole chip is encapsulated in a gold-plated Kovar housing to obtain well performance and high reliability.
