Overview

The Thin Film Lithium Niobate Fiberoptic Modulators (TLNM) series offers a low driving voltage of 3.5V and broadband operation up to 110 GHz, delivering exceptional efficiency and performance over traditional Lithium Niobate modulators. Leveraging thin-film LiNbO₃ technology, its reduce size waveguides optimize RF-to-optical conversion, making it ideal for ultra-high-frequency electrical-to-optical applications. A built-in bias control section with a micro-heater and photodetector ensures stable optical biasing via advanced feedback circuitry. High-speed modulation is facilitated through an SMA connector, with bias control applied via pins, while an optional automatic bias controller provides enhanced stability. Custom designs are available to meet specific application needs.
