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 broadband electro-optic amplitude modulator (EOAM-BB) is a device that achieves optical wave amplitude modulation based on the electro-optic effect. It is composed of two electro-optic crystals, with the driving voltage applied directly across both ends of the crystals, and a half-wave voltage on the order of several hundred volts. This series features a wide operating frequency range and is widely used in optical communications, Quantum Technologies information processing, optical experiments, and other fields. By applying voltage to change the propagation characteristics of light waves in electro-optic materials, amplitude or polarization modulation can be achieved. During use, it can be paired with an external high-voltage driver, or a "low-voltage signal source + power amplifier" combination scheme can be used to achieve flexible driving.

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 High-Frequency Electro-Optic Modulator Driver HF-EOMD provided by LBTEK is mainly used for high-frequency EOMs and can drive the EOMPR series of electro-optic modulators. The driver integrates a signal source and an amplifier internally, offering high integration. Depending on the compatible EOM, the signal source can generate frequency signals from 1 GHz to 15 GHz, which are amplified by the amplifier to a maximum output of 35 dBm.

Note:

The output frequency of this product's driver is limited by the internal amplifier's bandwidth. When shipped from the factory, the operating frequency range of the driver will be preset according to the customer's actual application requirements.

Please specify the operating frequency and required modulation power of the electro-optic modulator (EOM) when placing an order. We will then configure the optimal driving output range (typical configuration: "center frequency ± 50 MHz"). If not specified, the frequency cannot be arbitrarily adjusted beyond the amplifier's bandwidth after shipment. Please be aware of this.

LBTEK RF Power Amplifier (RFPA) is a functional module designed to amplify low-amplitude radio frequency (RF) signals. Operating in the frequency range of 2 MHz to 500 MHz, it provides effective power amplification even at frequencies as low as 2 MHz. Powered by a standard 9–15 V commercial power supply, the amplifier delivers a maximum output power of ≥1 W and is suitable for driving broadband electro-optic phase modulators.
