Optical microbubble resonator [PDF]
We develop a method for fabricating very small silica microbubbles having a micrometer-order wall thickness and demonstrate the first optical microbubble resonator. Our method is based on blowing a microbubble using stable radiative CO(2) laser heating rather than unstable convective heating in a flame or furnace.

Optical Microdiscus Resonators [PDF]
We present a new “soften-and-squash” method for turning microspheres into high quality, stand-alone microdiscus resonators. Due to the annealing involved in the fabrication process, their measured Q factors are one order of magnitude better than the starting microspheres.

Resonant Optical Antennas [PDF]
We have fabricated nanometer-scale gold dipole antennas designed to be resonant at optical frequencies. On resonance, strong field enhancement in the antenna feed gap leads to white-light supercontinuum generation. The antenna length at resonance is considerably shorter than one-half the wavelength of the incident light.

Self-tuning optical resonator [PDF]
We demonstrate a nonlinear optical resonator that tunes itself onto resonance with an input beam. In a monolithic Fabry-Perot cavity implemented in rubidium-doped periodically-poled potassium titanyl phosphate, an intensity-dependent refractive index produces line-pulling by multiple free-spectral ranges (FSRs).

In-band label extractor based on Cascaded Si ring resonators enabling 160 Gb/s optical packet switching modules [PDF]
Photonic integration of optical packet switching modules is crucial to compete with existing electronic switching fabrics in large data center networks.

Optical detection of magnetic resonance [PDF]
Abstract. The combination of magnetic resonance with laser spectroscopy provides some interesting options for increasing the sensitivity and information content of magnetic resonance. This review covers the basic physics behind the relevant processes, such as angular momentum conservation during absorption and emission.

Chasing the thermodynamical noise limit in whispering-gallery-mode resonators for ultrastable laser frequency stabilization. [PDF]
Ultrastable high-spectral-purity lasers have served as the cornerstone behind optical atomic clocks, quantum measurements, precision optical microwave generation, high-resolution optical spectroscopy, and sensing.

Feshbach resonances in an optical lattice [PDF]
We present the theory for ultracold atomic gases in an optical lattice near a Feshbach resonance. In the single-band approximation the theory describes atoms and molecules which can both tunnel through the lattice. Moreover, an avoided crossing between the two-atom and the molecular states occurs at every site.

Transmission and group delay of microring coupled-resonator optical waveguides [PDF]
We measured the transmission and group delay of microring coupled-resonator optical waveguides (CROWs). The CROWs consisted of 12 weakly coupled, microring resonators fabricated in optical polymers (PMMA on Cytop).

Nonlinear Optics in Microspherical Resonators
Nonlinear frequency generation requires high intensity density which is usually achieved with pulsed laser sources, anomalous dispersion, high nonlinear coefficients or long interaction lengths. Whispering gallery mode microresonators (WGMRs) are photonic devices that enhance nonlinear interactions and can be exploited for continuous wave (CW ...
