“…This leads to enhanced mode confinement resulting in higher Q and also in increased mode diameter and hence increased lasing wavelength. [16] This build-up process behavior was typical and was applied to different QR samples. Such a pre-prepared area then yields robust lasing and shows the typical threshold behavior as demonstrated in Figure 2.…”

An efficient method for preparation of semiconductor quantum rod films for robust lasing in a cylindrical microcavity is reported. A capillary tube, serving as the laser cavity, is filled with a solution of nanocrystals and irradiated with a series of intense nanosecond laser pulses to produce a nanocrystal film on the capillary surface. The films exhibit intense room‐temperature lasing in whispering‐gallery modes that develop at the film–capillary interface as corroborated from the spacing detected for the lasing modes. Good lasing stability is observed at moderate pump powers. The method was applied successfully to several quantum‐rod samples of various sizes.

Optofluidic dye lasers are microfabricated liquid dye lasers enabled by the microfluidics technology. The integration of dye lasers with microfluidics not only facilitates the implementation of complete ''lab-on-a-chip'' systems, but also allows the dynamical control of the laser properties which is not achievable with solid-state optical components. We review the recent demonstrations of onchip liquid dye lasers and some of the pre-microfluidics era microscopic dye lasers which are also amenable to microfluidic implementation. Potential applications and future directions are discussed.

“…Microdisk lasers based on non-crystalline materials (polymer 22 and dye solution 23 ) have also been reported. For this materials n ≈ 1.8 is smaller and the values of M (930 in 22 and 3000 in 23 ) are high.…”

Microdisk resonator with a linear defect at some distance away from the circumference is studied theoretically. We demonstrate that the presence of the defect leads to (i) enhancement of the output efficiency, and (ii) directionality of the outgoing light. The dependence of the radiative losses and of the far-field distribution on the position and orientation of the defect are calculated. The angular dependence of the far field is given by a lorentzian with a width that has a sharp minimum for a certain optimal orientation of the defect line. For this orientation the whispering-gallery mode of a circular resonator is scattered by the extended defect in the direction normal to the disk boundary.
