Microbend gratings

Microbend gratings, often referred to in the context of optical fibers and photonic devices, are a type of optical grating that utilize micro-bending as a mechanism for light modulation. They are primarily designed to manipulate light within optical communication systems, sensors, and other photonic applications. ### Key Features: 1. **Structure**: Microbend gratings consist of a series of small bends or imperfections introduced into the optical fiber or waveguide.
