Free-Space Wide-Aperture Sheet-Isolator Based on a Multilayered Resonant Cavity
R. Kononchuk, C. Pfeiffer, I. Anisimov +3
We introduce the first conceptual design of a free-space thin-sheet isolator with unlimited aperture and the possibility of a broadband omnidirectional rejection of the backward pr…
Label-Free Nanoscopy with Contact Microlenses: Super-Resolution Mechanisms and Limitations
Vasily N. Astratov, Farzaneh Abolmaali, Aaron Brettin +5
Despite all the success with developing super-resolution imaging techniques, the Abbe limit poses a severe fundamental restriction on the resolution of far-field imaging systems ba…
Experimental Realization of a Reflective Optical Limiter
Jarrett H. Vella, John H. Goldsmith, Andrew T. Browning +4
Optical limiters transmit low-intensity light, while blocking laser radiation with excessively high intensity or fluence. A typical passive optical limiter absorbs most of the high…
Movable thin films with embedded high-index microspheres for super-resolution microscopy
Kenneth W. Allen, Navid Farahi, Yangcheng Li +5
Microsphere-assisted imaging emerged as a surprisingly simple way of achieving optical super-resolution imaging. In this work, we use movable PDMS thin films with embedded high-ind…
Demonstration of whispering-gallery-mode resonant enhancement of optical forces
Yangcheng Li, Alexey V. Maslov, Nicholaos I. Limberopoulos +1
We experimentally studied whispering-gallery modes(WGMs) and demonstrated resonance enhancement of optical forces evanescently exerted on dielectric microspheres. We showed that th…
Spectrally resolved resonant propulsion of dielectric microspheres
Yangcheng Li, Alexey V. Maslov, Nicholaos I. Limberopoulos +2
Use of resonant light forces opens up a unique approach to high-volume sorting of microspherical resonators with much higher uniformity of resonances compared to that in coupled-ca…
