Broadband Electro-Optic Phase Modulator
The Broadband Electro-Optic Phase Modulator(Non-resonant Phase Modulator) operates on the principle of the electro‑optic effect to achieve precise phase modulation of optical signals. It offers an ultra‑broad operating frequency range, supporting continuous operation from DC up to 100 MHz. Featuring a half‑wave voltage below 300 V, the series supports flexible driving configurations: direct operation with an external high‑voltage driver, or combination with a low‑voltage signal source and power amplifier to fulfill diverse modulation demands. The EOPM is equipped with a 2/3 mm clear aperture and adopts a standard SMA electrical interface.
