Rof Electrical Optical Modulator Y Waveguide Modulator LINBO3 Phase Modulation

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.

Applications:

1. Fiber optical gyroscope (FOG)
2. Fiber Optic Current Sensor (FOCS)
3. Hydrophones and other optical fiber sensing fields
