Glass Raman Spectrum

Glass is an amorphous solid that exhibits a limited short-range order and, unlike crystal lattices with infinite periodicity, retains a completely random organization structure on a long-range scale. Glass is most often formed by the rapid cooling of the molten form. It is widely used in fiber optics, namely, communication lines – the basis of the Internet; telephone and local television networks; and optical signal distribution devices.

Raman spectroscopy of Glass

Raman scattering in telecommunication networks requires materials with broad Raman gain profiles. For example, silica is known for its very low loss and ability to serve as a carrier medium, although it has a relatively low gain. Spontaneous Raman spectroscopy has proven an effective method of express evaluation of the glass Raman gain coefficient over a wide frequency range. Raman amplifiers have also been growing in popularity due to the development of broadband optical fiber.
