Generation of vector beams at 1550 nm telecommunications wavelength using a segmented q-plate

Journal article (SPIE) reports generation of vector beams at 1550 nm using a segmented q-plate. Published 2016-03-23.

Experimentally measured attenuation of silica core optical fiber. At 1550 nm wavelength attenuation components are determined as follows: Rayleigh scattering loss ~ 0.1200 dB/km, infrared absorption loss ~ 0.0150 dB/km, Impurity absorption loss ~ 0.0047 dB/km, waveguide imperfection loss ~ 0.0010 dB/km.
