General Description
Photonics of Crystals (POC) Fiber-Coupled Acousto-Optic Modulators (FAOM) leverage the principles of bulk wave acousto-optic interaction for precise control of optical beam intensity and frequency. These modulators combine high-performance modulation capabilities with the convenience of fiber coupling, ensuring reliable operation in advanced optical systems.
The FAOM is designed to modulate both the amplitude of optical pulses and the frequency shift of light. Its modulation speed is dictated by the rise time of the output pulses, enabling high-speed, low-latency applications. POC’s FAOMs employ fiber coupling to enhance operational efficiency and simplify integration, providing advantages over free-space devices such as reduced alignment complexity and higher system reliability.
Available in polarization-maintaining and non-polarization-maintaining configurations, these modulators operate at frequencies up to 300 MHz and are tailored for various applications, including sensor communications, quantum technology, and industrial lasers. Customization options are available for fiber termination (bare fiber, FC/APC connectors), wavelength, and parameter indicators, ensuring optimal performance across diverse environments.
