In this study, a fiber optical tweezer is successful integrated for trapping polystyrene particles at the wavelength of 650 nm. The experimental results show that the optimal trapping efficiency of 4.3% occurs at the working distance of 26 μm.
In this paper, the trapping efficiencies of the optical tweezer with different laser wavelength are studied by capturing a microparticle. The best trapping efficiency of the optical trapping occurs at the wavelength of 532 nm. In addition, the experiment of trapping yeast is also conducted at the wavelength of 650 nm. The corresponding trapping efficiency is found to be 2.80 %.
We propose a new and ultracompact microcavity fiber Fabry-Pérot interferometer (MCFFPI) based on an ultrathin film of gold (Au) embedded in a single-mode fiber endface. The interference fringes of the proposed configuration with different cavity length are observed experimentally and verified the interference patterns are from the combination of Au thin film reflector and Fresnel reflection of fiber...
We propose an ultracompact microcavity fiber Fabry–Pérot interferometer (MCFFPI) based on an ultrathin film of gold (Au) embedded in a single-mode fiber endface. The embedded Au thin film splits the input light into two paths for interference. The interference fringes of the proposed configuration with different cavity lengths are observed experimentally, and we verify that the interference patterns...
