Viewpoint “ Snowflake Crystal ” Traps Light and Sound
Research on cavity optomechanics, which concerns the interaction between light and mechanical vibrations in confined geometries, has blossomed during the past few years [1]. Potential applications include coherent microwave–optical conversion, sensitive mechanical measurements, quantum information processing, mechanical storage of light pulses, and coupling between different quantum systems, as...
متن کاملLight Traps
In the February 1992 issue of the American Mathematical Monthly, J. E. Connett [1] asked whether it is possible to construct a 'light trap': a re ective-sided container with the property that a beam of light, shone into it from an appropriate direction, would be re ected inside it over and over again and never escape. Connett suggests that such a trap might be of value as a device to store ligh...
متن کاملPosition and Intensity Modulations in Holographic Optical Traps Created by a Liquid Crystal Spatial Light Modulator
The addressing of the liquid crystals in spatial light modulators gives rise to temporal modulation of the phase pattern. Here we investigate the effect of this on the intensity and position of holographic optical traps. We use high-speed camera imaging of the laser spots back-reflected off the sample cover slip to determine the integrated pixel intensity and track the position of a laser spot....
متن کاملThe effect of high frequency sound on Culicoides numbers collected with suction light traps.
Culicoides midges (Diptera: Ceratopogonidae), are involved in the transmission of various pathogens that cause important diseases of livestock worldwide. The use of insect repellents to reduce the attack rate of these insects on livestock could play an important role as part of an integrated control programme against diseases transmitted by these midges. The objective of this study was to d...
