Abstract

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