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 high-frequency resonant electro-optic phase modulators are based on the electro-optic effect and optical resonant cavity principles to achieve optical signal phase modulation. Utilizing the resonance principle, resonant electro-optic phase modulators can effectively reduce the half-wave voltage and increase the modulation depth. The resonant frequency of the EOPMR series high-frequency resonant electro-optic phase modulators is adjustable and can be tuned via the adjustment knob on the device. The signal interface type is SMA. The bottom of the device features M4 threaded holes for easy mounting onto posts. The polarization direction of the incident light must align with the label on the input end.

The HF-EOMD high-frequency electro-optic modulator driver provided by LBTEK is primarily used for high-frequency EOMs and can drive the EOPMR series of electro-optic modulators. Depending on the compatible EOM, the signal source can generate frequency signals ranging from 1GHz to 15GHz, amplified to a maximum output of 35 dBm.

LBTEK's RF Power Amplifier (RFPA) is a functional module designed to amplify low-amplitude radio frequency (RF) signals. It operates primarily within the 2 MHz to 500 MHz frequency band, providing power amplification even at frequencies as low as 2 MHz. Powered by a standard 9-15 V DC power supply, it can deliver a maximum output power of ≥1 W. This amplifier is suitable for driving traveling-wave electro-optic phase modulators.
