Photophoretic Trapping: Fundamentals, Advances and Future Directions
Anita Pahi, Kirty Ranjan Sahoo, Souvik Sil +1
Photophoretic forces, several orders of magnitude stronger than radiation pressure, enable particle trapping at remarkably low optical intensities and have opened pathways to appli…
An ultra-stable three-dimensional photophoretic trap in air facilitated by a single multimode fiber
Souvik Sil, Anita Pahi, Aman Anil Punse +1
Photophoretic forces - which are of thermal origin - have defined an alternative route of optical trapping of absorbing microparticles in air. Here, we show that a single multi-mod…
Trapping multiple absorbing particles in air using an optical fiber by photophoretic forces
Souvik Sil, Anita Pahi, Aman Anil Punse +1
We demonstrate photophoretic force-based optical trapping of multiple absorbing particles in air by loosely focusing a Gaussian beam with a series of convex lenses of different foc…
