dc.description.abstract | We report on the fabrication and characteristics of a step-index glass-clad polymer optical fiber that uses a novel
fluorescent stilbenoid compound for lasing and amplification applications. The compound, 1,4-bis(4-diphenyl-
amino-styryl)-benzene, is specifically designed for the blue region of the spectrum and has a very high quan-
tum yield of 0.85 in a solid-state polymer host and a large Stokes shift. Significant spectral narrowing and
superlinear increase of output intensity are observed under photoexcitation at 355 nm, which are indicative
of the occurrence of amplified spontaneous emission. By means of gain spectroscopy, a large optical gain of
up to
36
cm
2
1
at 494 nm has been obtained for the fiber when it is transversely photoexcited at
12
mJ
cm
2
.
The waveguide loss has been measured to be
0.7
cm
2
1
at 494 nm. The demonstration of high gain and
low waveguide loss has favorable implications for the construction of a very compact, tunable coherent light
source. | en |
