Paper Abstract

A three-fiber probe is fabricated for the measurement of fluorescent light emitted from a flat and tilted membrane cast on a glass substrate. With two identical photonic crystal fibers (PCFs) as the receiving fibers, we demonstrate that a segment of pure glass rod formed at the front end of a large-core PCF has an enhanced capability of collecting fluorescent light. The percentage of this increase depends on the distance between the membrane and the fiber probe. An initial theoretical investigation reveals that a longer fused segment can shift the light reception cone towards the symmetric axis of the illuminating fiber where the maximum energy locates. Higher emission is expected in this area and would be able to reach this shifted reception cone. This area is a dead zone for the PCF without or with a shorter fused segment. The possible applications of this fused glass segment with a proper length are highlighted.
