A theory of Bose-Einstein condensation of light in a dye-filled optical microcavity is presented. The theory is based on the hierarchical maximum entropy principle and allows one to investigate the fluctuating behavior of the photon gas in the microcavity for all numbers of photons, dye molecules, and excitations at all temperatures, including the whole critical region. The master equation desc...

We demonstrate theoretically and experimentally that a specifically designed microcavity driven in the optical parametric oscillation regime exhibits lighthouse-like emission, is, an emission focused around single direction. Remarkably, direction of this microlighthouse is continuously controlled by linear polarization incident laser, angular beam steering over 360° demonstrated. Theoretically,...

Whispering gallery modes (WGM) resonators (K. J. Vahala, 2003; A. B. Matsko et al., 2006) have been extensively studied in a large variety of geometrical shapes and in a wide range of promising studies and applications (A. Chiasera et al., 2010), both fundamental like CQED and practical like low threshold lasers and sensors. The Silica spherical microresonators, made from commercial optical fib...

The authors demonstrate photoluminescence lifetime and intensity control in a near-infrared dye embedded all-polymer microcavity.

A key challenge for silicon photonic systems is the development of compact on-chip light sources. Thulium-doped fiber and waveguide lasers have recently generated interest for their highly efficient emission around 1.8 μm, a wavelength range also of growing interest to silicon-chip based systems. Here, we report on highly compact and low-threshold thulium-doped microcavity lasers integrated wit...

Chip-scale, optical microcavity-based biosensors typically employ an ultra-high-quality microcavity and require a precision wavelength-tunable laser for exciting the cavity resonance. For point-of-care applications, however, such a system based on measurements in the spectral domain is prone to equipment noise and not portable. An alternative microcavity-based biosensor that enables a high sens...

Abstract We implement a simple method for fast and precise delivery of ultracold atoms to microscopic device, i.e. Fabry–Perot microcavity. By moving single beam optical dipole trap in direction perpendicular the axis with an acousto-optical deflector, we transport up 1 million within 100 ms over cm. Under these conditions, efficiency above 95% is achieved only minimal heating. The atomic cloud...

Personalized medicine has the potential to improve our ability to maintain health and treat disease, while ameliorating continuously rising healthcare costs. Translation of basic research findings to clinical applications within regulatory compliance is required for personalized medicine to become the new foundation for practice of medicine. Deploying even a few of the thousands of potential di...
