CHAOTIC MICROLASERS BASED ON DYNAMICAL LOCALIZATION [PDF]
International Journal of Bifurcation and Chaos, 2004 We report the first direct observation of lasing action from a dynamically localized mode in a microdisk resonator with rough boundary. In contrast to microlasers based on stable ray trajectories, the performance of our device is robust with respect to the boundary roughness and corresponding ray chaos, taking advantage of Anderson localization in ...

Switchable lasing in coupled multimode microcavities [PDF]
, 2007 We propose the new concept of a switchable multimode microlaser. As a generic, realistic model of a multimode microresonator a system of two coupled defects in a two-dimensional photonic crystal is considered.

Erbium-doped and Raman microlasers on a silicon chip fabricated by the sol–gel process [PDF]
, 2005 We report high-Q sol–gel microresonators on silicon chips, fabricated directly from a sol–gel layer deposited onto a silicon substrate. Quality factors as high as 2.5×10^7 at 1561 nm were obtained in toroidal microcavities formed of silica sol–gel ...

Experimental demonstration of a novel heterogeneously integrated III-V on Si microlaser [PDF]
, 2013 In this work we present the first experimental demonstration of a novel class of heterogeneously integrated III-V-on-silicon microlasers. We first show that by coupling a silicon cavity to a III-V wire, the interaction between the propagating mode in the

Room-Temperature Continuous-Wave Vertical-Cavity Single-Quantum-Well Microlaser Diodes [PDF]
, 1989 Room-temperature continuous and pulsed lasing of vertical-cavity, single-quantum-well, surface-emitting microlasers is achieved at ~983nm. The active Ga[sub][0-8]In[sub][0-2]As single quantum well is 100 [angstroms] thick.
