Abstract
A splice with core-writing technology includes: (a) two fiber ends aligned and separated by a gap in a mechanical alignment system containing a polymerizable resin composition and photoinitiators; (b) the core bridge is written by launching UV or visible light through one or both fibers to be connected; and (c) the cladding is formed by flooding light or by thermal curing of polymerizable material to obtain the required refractive index contrast for waveguiding. The splice can be between two fibers, one of which is a connectorized stub. The fibers can be arranged in parallel or in optical alignment with a reflective device.
