Whispering-gallery mode terahertz pulses.
We report what is to our knowledge the first observation of a subpicosecond terahertz (THz) pulse propagating as a superposition of the whispering-gallery modes (WGMs) of a dielectric cylinder. The WGM THz pulses are coupled into and out of a 5-mm-diameter silicon cylinder via a 100-mum -thick, single-mode silicon slab waveguide. We observed two round-trip cylindrical cavity pulses from this co...
متن کاملOptical Second Harmonic Generation in a Whispering Gallery Mode Resonator
We are developing high quality factor whispering gallery mode resonator (WGMR) disks for use in quantum information experiments. Our polished lithium niobate disks achieved a quality factor on the order of 10. We report the use of Type-I noncritical phase matching in a lithium niobate whispering gallery mode resonator disk to produce optical second harmonic generation at λ = 532nm. This process...
متن کاملPerformance of Eudragit Coated Whispering Gallery Mode Resonator-Based Immunosensors
Whispering gallery mode resonators (WGMR) are an efficient tool for the realization of optical biosensors. A high Q factor preservation is a crucial requirement for good biosensor performances. In this work we present an Eudragit®L100 coated microspherical WGMR as an efficient immunosensor. The developed resonator was morphologically characterized using fluorescence microscopy. The functionaliz...
متن کاملBrillouin lasing with a CaF2 whispering gallery mode resonator.
Stimulated Brillouin scattering with both pump and Stokes beams in resonance with whispering gallery modes of an ultrahigh Q calcium fluoride resonator is demonstrated for the first time. The resonator is pumped with 1064 nm light and has 3 muW Brillouin lasing threshold. The scattering is observed due to the unique morphology of the resonator reducing the phase mismatch between the optical mod...
متن کاملQuantum light from a whispering-gallery-mode disk resonator.
Optical parametric down-conversion has proven to be a valuable source of nonclassical light. The process is inherently able to produce twin-beam correlations along with individual intensity squeezing of either parametric beam, when pumped far above threshold. Here, we present for the first time the direct observation of intensity squeezing of -1.2 dB of each of the individual parametric beams ...
