Subwavelength silicon microcavities
We present a study of the first silicon microdisk resonators which are smaller than the free-space resonant wavelength in all spatial dimensions. Spectral details of whispering gallery modes with azimuthal mode number m = 4-7 are measured in microdisks with diameters between 1.35 and 1.89microm and are studied at wavelengths from 1.52 to 1.62microm ...

Design and fabrication of high quality-factor 1-d photonic crystal/photonic wire extended microcavities [PDF]
We have successfully demonstrated experimentally the fabrication and measurement of high quality-factor one-dimensional photonic crystal/photonic wire extended cavities based on silicon-on-insulator.

The synovial cavity and its fluid are essential for joint function and lubrication, but their developmental biology remains largely obscure. Here, we analyzed E12.5 to E18.5 mouse embryo hindlimbs and discovered that cavitation initiates around E15.0 ...

Quantum Coherence and Total Phase in Semiconductor Microcavities for Multi-Photon Excitation
We examine how the weak excitation regime of a quantum well confined in a semiconductor microcavity (SM) influences the dynamics of quantum coherence and the total phase. We analyze the impact of the physical parameters on different quantumness measures,

Ultrasound sensing with optical microcavities [PDF]
Nowadays, ultrasound sensors are playing an irreplaceable role in the fields of biomedical imaging and industrial nondestructive inspection. Currently, piezoelectric transducers are the most widely used ultrasound sensors, but their sensitivities drop ...

Switchable Lasing in Multimode Microcavities [PDF]
We propose the new concept of a switchable multimode microlaser. As a generic, realistic model of a multimode microresonator a system of two coupled defects in a two-dimensional photonic crystal is considered. We demonstrate theoretically that lasing of the cavity into one selected resonator mode can be caused by injecting an appropriate optical pulse ...

Prospects in Broadening the Application of Planar Solution‐Based Distributed Bragg Reflectors
Distributed Bragg reflectors (DBRs) are primarily used in lasers and telecommunications. Liquid film deposition of DBRs holds great promise for expanding their utilization in environmental friendly, low‐cost, and large‐area applications.

The optical control of phase locking of polariton condensates
The phase and the frequency of an exciton polariton condensate excited by a nonresonant pump can be efficiently manipulated by an external coherent light.

Advances of Optofluidic Microcavities for Microlasers and Biosensors
Optofluidic microcavities with high Q factor have made rapid progress in recent years by using various micro-structures. On one hand, they are applied to microfluidic lasers with low excitation thresholds.

Compared to organic emitters, perovskite materials generally have a small Stokes shift and correspondingly large re‐absorption of dipole emission. Classical optical modelling methods ignoring re‐absorption do not provide an adequate description of the ...
