Definition
The 10GHz ultra-long phase modulator is a high-performance phase modulator designed specifically for the C-band, manufactured using lithium niobate (LiNbO3) material. This modulator boasts a 10GHz bandwidth and enables efficient phase modulation at low drive voltages, making it suitable for high-speed, high-capacity optical communication and optical signal processing systems. It is fabricated using annealed proton-switched (APE) waveguides and employs polarization-maintaining (PM) input and output fibers to ensure stable polarization of the optical signal during transmission.
