Bragg reflector
WebBragg gratings in optical fibers reflect a specific wavelength dependent on the period of the gratings and the refractive index of the optical fiber. This calculator finds the period of Bragg grating needed for a predetermined wavelength and index of refraction. WebJul 6, 2024 · Distributed Bragg reflectors (DBRs) are structures that are made from alternating layers of different refractive index. They can be highly reflective and the stopband of the reflection peak is tuneable by varying the optical thickness of the constituent layers.
