LBTEK's resonant electro-optic phase modulator (EOPM) is a device that achieves optical signal phase modulation based on the electro-optic effect and optical resonant cavity principle. This modulator selects lithium niobate with outstanding performance as the electro-optic crystal material. When an electric field is applied to the crystal, its refractive index changes, thereby generating a phase modulation effect on the optical signal passing through the crystal. The EOPM has a clear aperture of 3 mm and uses an SMA signal interface. Additionally, depending on the laser incidence direction, it offers flexible choices between horizontal and vertical polarization orientations, providing high adaptability for various application scenarios.

LBTEK's Broadband Electro-Optic Phase Modulator (EOPM-BB) is a device that modulates the phase of optical signals based on the electro-optic effect principle. It features an extremely wide operating frequency range, functioning at any frequency from DC to 100 MHz. In terms of driving methods, this series has a half-wave voltage of 258V and supports two driving schemes: it can be used directly with an external high-voltage driver or through a combination of a "low-voltage signal source + power amplifier" to meet modulation requirements. The EOPM-BB has a clear aperture of 3 mm and uses an SMA signal interface. Additionally, depending on the laser incident direction, it offers flexible selection between horizontal and vertical polarization directions, providing high adaptability for various application scenarios.

LBTEK's Power Amplifier (RFPA) is a functional module that amplifies small radio frequency signals, primarily operating in the frequency range of 10MHz-300MHz. It utilizes a 24V commercial power supply, with a maximum output of 2W, and can be used to drive traveling-wave electro-optic phase modulators.
