Bragg reflector 원리
Bio-inspired Bragg Reflectors are 1D photonic crystals inspired by nature. Reflection of light from such a nanostructured matter results in structural colouration. When designed from mesoporous metal-oxides or polymers, these devices can be used as low-cost vapor/solvents sensors. For example, colour of … See more A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers. It is a structure formed from multiple layers of alternating materials with varying refractive index, or by periodic variation of some … See more The DBR's reflectivity, $${\displaystyle R}$$, for intensity is approximately given by where $${\displaystyle n_{o},\ n_{1},\ n_{2}}$$ and $${\displaystyle n_{s}\,}$$ are the respective refractive indices of the originating medium, … See more • Bragg's law – Physical law regarding scattering angles of radiation through a medium • Bragg diffraction – Physical law regarding scattering angles of radiation through a medium • Diffraction – Phenomenon of the motion of waves See more WebAbout Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ...

Webwaveguides, and Bragg reflectors. From the results of this study it has been found that a cylindrical perforated waveguide with a Bragg Reflector as a cladding, is one way to overcome the chromic dispersion of optical fiber materials. This is because the electromagnetic waves traveling through the air (n=1) do not experience dispersion.
