We report the first experimental demonstration of cavity-induced resonances that occur without total internal reflection. We obtained these resonances by observing the fluorescence spectrum from the molecules enclosed within a small, lossy capillary

We studied the angular distribution of fluorescence from a small, lossy capillary filled with a laser-dye solution. We found that the fluorescence is isotropic for the liquid core and that, far from the liquid–solid phase transition, this isotropy

The light-scattering Mueller matrix for an r approximately 2.0 microm radius, rough quartz fiber contains phase information different from that of a perfectly cylindrical fiber of the same optical constants and radius. The rough surface creates highe

Fluorescent angular scattering from laser dye-filled small-core-diameter fibers shows increased backscattered fluorescent emissions as the core diameter decreases below 23 microm. The fluorescent angular scattering from Coumarin 7 laser dye-filled ho

The light-scattering Mueller matrix for an r = 0.345-microm-radius quartz fiber, illuminated at lambda = 0.4416 microm, is examined as a function of contamination with MgO crystals. When the MgO contamination is low, the matrix elements resemble thos

The entire sixteen-element light scattering matrix is experimentally determined for a circular cross-sectioned conducting fiber illuminated with lambda = 632.8-nm radiation at normal incidence. The radius (1.552 +/- 0.007) microm, determined by compa

We used sub-microm-sized quartz fibers to probe a visible light, standing electromagnetic wave inside a laser ring cavity. By observing variations in the cavity's irradiance decay lifetime, we observed the longitudinal shape of the standing wave.

The angular distribution of scattered light depends on the electromagnetic properties (refractive index, absorptivity), the geometrical properties (size, shape, and distribution) of the scatterer(s), as well as the polarization and illumination angle

Light scattered from a perfect cylindrical quartz fiber was studied as a function of fiber rotation, bend, bend and rotation, and tilt. These pure geometrical manipulations are basic and easily controlled perturbations that affect both the total inte

Scattering from an apparently perfect fiber, placed perpendicular to a laser beam, produces an out of plane scattering pattern containing an internal structure not predicted by simple fiber scattering theory. A photographic study of light scattered f
