Compound parabolic tapered fiber for fiber coupling with a highly divergent source

Appl Opt. 2004 Nov 10;43(32):5923-5. doi: 10.1364/ao.43.005923.

Abstract

A novel fiber tapering shape, which is based on compound parabolic geometry, is proposed to increase the acceptance angle of a compound parabolic concentrator. The proposed design is described by use of ray optics on a step-index multimode fiber.
