A micron-sized liquid droplet acts as a very high-quality factor optical cavity. The cavity modes are referred to as morphology-dependent resonances (MDRs), which are sensitive to the droplet size, shape, and inclusions. The MDRs greatly lower the in

We have observed that in a binary mixture microdroplet, stimulated Raman scattering (SRS) from the highest-gain mode of the majority species pumps the SRS from the minority species and a weaker-gain mode of the majority species more efficiently than

A method is presented for calculating the quality factors (Q's) and the effective-average gain and loss coefficients for the modes of a dielectric sphere which has a spatial perturbation of the imaginary part of the refractive index. The method is ap

Temperature-dependent wavelength shifts of dye lasing in microdroplets with a thermochromic additive

Optics letters. 20(16)
The lasing spectra from a Rhodamine B–doped microdroplet (85% isopropanol and 15% water) with a thermochromic additive (CoCl2.6H2O) have been observed to shift progressively toward blue as the droplet temperature is gradually increased. The absorpt

The frequencies of the normal azimuthal modes of a slightly deformed droplet that is axisymmetric about its flow direction are no longer degenerate but vary with position along the droplet rim. We measured the wavelength variation along the entire ri

High-Q morphology-dependent resonances (MDR's) in microdroplets provide optical feedback for nonlinear processes such as stimulated Raman scattering (SRS). The SRS signal from weaker gain modes or from the minority species in a binary mixture droplet

Optical scattering by fuel droplets of spray jets can provide information about droplet evaporation in a combustion chamber. Evaporating fuel droplets are often spatially inhomogeneous and non-spherical. Spatial inhomogeneities in droplets can occur

With addition of an absorber to dye-doped microdroplets, an absorption-dependent blue shift in the lasing spectra has been observed. The better the spectral overlap between the absorption and the fluorescence spectra of the dye, the larger the blue s
