Photodetector Focal Plane Arrays Integrated with Silicon Micropyramidal Structures in MWIR
Grant W. Bidney, Joshua M. Duran, Gamini Ariyawansa +3
Light-concentrating truncated Si micropyramidal arrays with 54.7 degree sidewall angles were successfully integrated with PtSi Schottky barrier photodetectors. Four different devic…
Focusing and Diffraction of Light by Periodic Si Micropyramidal Arrays
Grant W. Bidney, Amstrong R. Jean, Joshua M. Duran +4
This research was devoted to modeling of the optical properties of Si micropyramids aimed at designing optimal structures for applications as light concentrators in mid-wave infrar…
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…
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…
Tuning the optical forces on- and off-resonance in microspherical photonics
Yangcheng Li, Alexey V. Maslov, Ana Jofre +1
Light pressure effect has been discovered long ago and has been used as an optical method to manipulate microand nanoparticles. It is usually considered as a nonresonant effect det…
