Higher order multiphoton-pumped polarized lasers have fundamental technological importance. Although they can be used to in vivo imaging, their application has yet to be realized. Here we show the first polarized three-photon-pumped (3PP) microcavity laser in a single host-guest composite metal-organic framework (MOF) crystal, via a controllable in situ self-assembly strategy. The highly orient...
A laser cavity formed from a single defect in a two-dimensional photonic crystal is demonstrated. The optical microcavity consists of a half wavelength-thick waveguide for vertical confinement and a two-dimensional photonic crystal mirror for lateral localization. A defect in the photonic crystal is introduced to trap photons inside a volume of 2.5 cubic half-wavelengths, approximately 0.03 cub...
We study theoretically optomechanical interactions in a semiconductor microcavity with embedded quantum well under the optical pumping by Bessel beam, carrying non-zero orbital momentum. Due to transfer of momentum from light phonons, can act as an acoustic circulator: it rotates propagation direction incident phonon certain angle clockwise or anticlockwise. heating and cooling effects, circula...
A coupler based on silicon spherical microcavities coupled to silicon waveguides for telecom wavelengths is presented. The light scattered by the microcavity is detected and analyzed as a function of the wavelength. The transmittance signal through the waveguide is strongly attenuated (up to 25 dB) at wavelengths corresponding to the Mie resonances of the microcavity. The coupling between the m...

The application of whispering gallery mode (WGM) microcavities for Nano detection and biosensing is a field of research seeing ongoing attention [1-15]. This method exploits the high quality-factor (Q) of the optical cavity for ultra-sensitive monitoring of shifts in the resonant wavelength. These resonant wavelength shifts are due to modifications in the optical properties of the resonator tha...
