The 40 GHz Multi-Band Lithium Niobate (LiNbO₃) Phase Modulator is a high-performance electro-optic device designed for high-speed optical communication, quantum optics, microwave photonics, and advanced optical signal processing. It enables precise control of the phase of an optical signal by applying an external RF (radio frequency) signal, making it a critical component in modern photonic systems.
Leveraging the superior electro-optic properties of lithium niobate, this phase modulator supports multi-band operation, allowing efficient modulation across a wide range of optical wavelengths and RF frequencies. Its capability to operate at frequencies up to 40 GHz makes it ideal for applications requiring ultra-fast signal modulation and low signal distortion.
The 40 GHz lithium niobate phase modulator operates based on the Pockels effect, which describes the change in the refractive index of a material in response to an externally applied electric field. By integrating a microwave electrode onto a lithium niobate waveguide, the device effectively modulates the phase of a transmitted optical signal.
Input Light: A continuous-wave (CW) laser signal is injected into the modulator’s optical waveguide.
RF Signal Application: A high-frequency RF signal (up to 40 GHz) is applied to the modulator’s electrodes, inducing a rapid change in the refractive index of the lithium niobate waveguide.
Phase Modulation: The optical wave experiences a phase shift proportional to the applied RF voltage, enabling precise phase modulation of the optical signal.
Output Signal: The phase-modulated optical signal exits the device, carrying encoded information that can be used for high-speed communications and advanced optical applications.
The 40 GHz Multi-Band Lithium Niobate Phase Modulator boasts several advanced features, including:
High Bandwidth: Supports modulation up to 40 GHz, suitable for high-speed optical communications.
Multi-Band Compatibility: Operates efficiently across multiple optical bands, including C-band (1530-1565 nm) and L-band (1565-1625 nm).
Low Insertion Loss: Provides high optical transmission efficiency with minimal signal attenuation.
High Linearity and Low Distortion: Ensures minimal signal degradation, making it ideal for advanced modulation formats such as QPSK (Quadrature Phase Shift Keying) and QAM (Quadrature Amplitude Modulation).
Stable and Reliable Performance: Lithium niobate is known for its excellent thermal and mechanical stability, ensuring reliable operation under various environmental conditions.
