“…However, the laser cavity is not formed by total internal reflection at the boundary. Otherwise, the spatial pattern of laser light would be a bright ring near the edge of the cluster [31]. We believe the three-dimensional (3-D) optical confinement in a micrometer-sized ZnO cluster is achieved through disorder-induced scattering and interference.…”

We review our recent work on lasing in active random media. Light scattering, which had been regarded as detrimental to lasing action for a long time, actually provided coherent feedback for lasing. The fundamental difference and transition between a random laser with coherent feedback and a random laser with incoherent feedback were illustrated. We also trapped laser light in micrometer-sized random media. The trapping was caused by disorder-induced scattering and interference. This nontraditional way of light confinement has important applications to microlasers.

“…Otherwise the spatial pattern of laser light would be a bright ring near the edge of the cluster. 27 We believe the 3D optical confinement in a micrometer-sized ZnO cluster is achieved through disorder-induced scattering and interference. Since interference effect is wavelength sensitive, only light at certain wavelengths can be confined in the cluster.…”

We review our recent work on lasing in active random media. Light scattering, which had been regarded detrimental to lasing action for a long time, actually provided coherent feedback for lasing. We also trapped laser light in micrometer-sized random media. The trapping was caused by disorder-induced scattering and interference. This nontraditional way of light confinement has important application to microlasers. The threshold of ranodm laser can be reduced by incorporating some degree of order into an active random medium. Our calculation result shows that by optimizing the degree of order one can dramatically reduce the threshold of random laser to the values comparable to those of photonic bandgap defect lasers.

“…More complex particles can also be added to the droplets with lasing being sustained. Water/glycerol droplets with Rh 6G and a fat emulsion (which is highly scattering) give enhancement of up to an order of magnitude in intensity output [86]. Droplets which would not normally lase can be made to do so by introducing the fat droplets ('intralipid').…”

“…As discussed in section 2.2.1 there was a range of early work making use of biological or biologically inspired material to produce droplet lasers [86,87,90,92,115]. A small jump in terms of practicality and functionality was made in [116] with the introduction of a superhydrophobic surface (a modified PLLA surface with a contact angle of 157°) to hold the droplets, in this case a vitamin B2 derived biomolecule, flavin mononucleotide, in water/ glycerol droplets, figure 4.…”

Abstract. It is perhaps surprising that something as fragile as a microscopic droplet could possibly form a laser. In this article we will review some of the underpinning physics as to how this might be possible, and then examine the state of the art in the field. The technology to create and manipulate droplets will be examined, as will the different classes of droplet lasers. We discuss the rapidly developing fields of droplet biolasers, liquid crystal laser droplets and explore how droplet lasers could give rise to new bio and chemical sensing and analysis. The challenges that droplet lasers face in becoming robust devices, either as sensors or as photonic components in lab on a chip devices is assessed.
