Advanced photonics applications require precision optical components manufactured with flexible customization capabilities and consistent performance. Standard optical modulators may not meet specific requirements for wavelength, modulation speed, fiber configuration, or system integration.

CASTECH designs and manufactures fiber-coupled acousto-optic modulators (FAOMs) with in-house production capabilities from optical design to final assembly. Based on bulk wave acousto-optic interaction technology, CASTECH FAOMs provide amplitude modulation and optical frequency shifting while offering advantages in integration, reliability, and operational convenience compared with free-space solutions.

With support for PM and non-PM fiber configurations, FC/APC connectors, customized wavelengths, RF parameters, and housing options, CASTECH delivers tailored FAOM solutions for fiber lasers, sensing systems, communication technologies, and quantum applications. The product portfolio supports frequencies up to 300 MHz and rise/fall times down to 6 ns, demonstrating CASTECH’s expertise in precision photonic component manufacturing.
