2. Premium Reflection Gratings (高级反射光栅) LightSmyth Technologies high efficiency reflection gratings are designed for use in telecom polarization-persity optics and laser frequency stabilization. These gratings are fabricated using projection lithography and reactive-ion-etch on a single-crystal-silicon substrate and metalized to achieve very high efficiency for a single polarization. Each grating is a master, not a replica, resulting in low scattered light and long lasting performance. Wafer-scale cost-effective fabrication allows us to offer very competitive prices.
Importantly, LightSmyth reflection gratings reduce scattered light up to 100X compared to conventional commercial replicated holographic gratings and mechanically ruled gratings, providing superior signal to noise ratio and low channel cross-talk. Advantages: Ultra-high efficiency for a single polarization. Robust dielectric materials, no polymers are used. Each grating is a master; ultra-low scatter. Highly competitive pricing; Telcordia-qualified.Applications: Optical telecommunications (laser sources, polarization persity systems) High power lasers Tunable lasers Specifications Optical
