High Delta, small core, single-mode fibers and their uses
Abstract:
High Delta, small core single-mode fibers were investigated with emphasis on clarifying both their fundamental optical characteristics and on possible uses. Preparation of such high Delta single-mode fibers through the vapor phase axial deposition process made it possible to achieve the low transmission losses of 0.82 dB/km (at 1.61 microm) for a 2.9%-Delta fiber and 0.68 dB/km (at 1.62 microm) for a 1.9%-Delta fiber. Measurements of fundamental characteristics such as transmission loss spectrum, bending loss, dispersion, stimulated Raman scattering, and frequency chirping were made for high Delta single-mode fibers. Two possible uses were investigated: a direct coupling experiment achieved 43% coupling efficiency between high Delta fiber and a LED, and an optical pulse compression experiment in the 1.5-microm wavelength region provided pedestal-free optical pulses with 1.2-ps (FWHM) width.
