Shifts in zero dispersion wavelength due to pressure, temperature and strain in dispersion shifted singlemode fibres

Abstract

Linear increases in the zero dispersion wavelength for increasing pressure, temperature and strain in a dispersion shifted fibre (DSF) have been observed. The shift arises as a result of an increasing differential refractive index between core and cladding, irrespective of the sign of the absolute refractive index change. © 1992, The Institution of Electrical Engineers.
