Description
High-performance, compact, fiber-coupled acousto-optic modulators
The Fiber-coupled acousto-optic modulators (FAOM) are based on the principle of bulk wave acousto-optic interaction, and have the ability to modulate both the amplitude of optical pulses and the frequency shift of light. The speed of FAOM is reflected by the rise time of the output optical pulses, and the modulation speed determines the response speed and available bandwidth of the system. FAOM adopts fiber coupling, which has the advantages of convenient operation, easy integration, and high reliability compared to free-space acousto-optic devices. It is widely used in fiber sensing systems, fiber lasers and other fields.
We have designed and developed a series of fiber-coupled (polarization-maintaining and non-polarization-maintaining) AOMs, with a maximum frequency of 300 MHz and a rise time as low as 6 ns. FAOMs can be customized with corresponding parameter indicators according to customer requirements, and the fiber end can also be equipped with FC/APC and other connectors as needed.
