چکیده
We demonstrate an ultra-sensitive sensor realized in high quality circular semiconductor micro-cavities employing radial Bragg reflectors. Resolution enhancement by a factor of ten, compared to conventional ring resonators, is demonstrated experimentally. ©2005 Optical Society of America OCIS codes: 230.5750 Resonators; 280.3420 Laser sensors

Ultra-High Sensitive Strain Sensor Based on Post-Processed Optical Fiber Bragg Grating
An ultra-high sensitive strain sensor is proposed. The sensing head, based on the post-processing of a fiber Bragg grating, is used to perform passive and active strain measurements. Both wavelength and full width half maximum dependences with the applied strain are studied for the passive sensor, where maximum sensitivities of 104.1 pm/με and 61.6 pm/με are respectively obtained. When combinin...
متن کاملUltra-sensitive chemical vapor detection using micro-cavity photothermal spectroscopy.
In this paper, I systematically investigated Micro-Cavity PhotoThermal Spectroscopy (MC-PTS), a novel technique for ultra-sensitive detection of chemical molecular species. I first derive the photothermal enhancement factor and noise characteristics of the technique using a generic theoretical model, followed by numerical analysis of a design example using chalcogenide glass micro-disk cavities...

Cavity quantum electro dynamics (CQED) involving (visible) light has attracted quite some attention since the fabrication of optical cavities with ultra-high quality factors (Q-factors) enabled the strong coupling between cavity photons and single optical emitters. The latter are typically established in form of optical transitions in cold atoms or excitonic transitions in molecules or quantum ...

A multi-longitudinal-mode fiber ring laser sensor is firstly proposed and experimentally demonstrated. Beat frequencies between any two longitudinal modes are used as sensing signal. The core component of the system is a multi-longitudinal-mode fiber ring cavity laser sensor based on beat frequency demodulation method. The theory of beat signal generation and strain measurement are discussed in...
