Chaotic microlasers Based on Dynamical Localization
We report the 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 angular momentum. The resonator design, although demo...
متن کاملDesign of beam splitters and microlasers using chaotic waveguides
We consider waveguides formed by single or multiple two-dimensional chaotic cavities connected to leads. The cavities are chaotic in the sense that the ray (or equivalently, classical particle) dynamics within them is chaotic. Geometrical parameters are chosen to produce a mixed phase space (chaotic regions surrounding islands of stability where motion is regular). Incoming rays (or particles) ...
متن کاملHigh-power directional emission from microlasers with chaotic resonators
High-power and highly directional semiconductor microcylinder lasers based on an optical resonator with deformed cross section are reported. In the favorable directions of the far-field, a power increase of up to three orders of magnitude over the conventional circularly symmetric lasers was obtained. A "bow-tie"-shaped resonance is responsible for the improved performance of the lasers in the ...
متن کاملIntracellular microlasers
Optical microresonators1 which confine light within a small cavity are widely exploited for various applications ranging from the realization of lasers2 and nonlinear devices3, 4, 5 to biochemical and optomechanical sensing6, 7, 8, 9, 10, 11. Here we employ microresonators and suitable optical gain materials inside biological cells to demonstrate various optical functions in vitro including las...
متن کاملReconfigurable Liquid Whispering Gallery Mode Microlasers
Engineering photonic devices from liquid has been emerging as a fascinating research avenue. Reconfigurably tuning liquid optical micro-devices are highly desirable but remain extremely challenging because of the fluidic nature. In this article we demonstrate an all-liquid tunable whispering gallery mode microlaser floating on a liquid surface fabricated by using inkjet print technique. We show...
