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…
Dual-mode optical fiber-based tweezers for robust trapping and manipulation of absorbing particles in air
Souvik Sil, Tushar Kanti Saha, Avinash Kumar +2
We develop an optical tweezers system using a single dual-mode optical fiber where mesoscopic absorbing particles can be trapped in three dimensions and manipulated employing photo…
Simultaneous measurement of mass and rotation of trapped absorbing particles in air
Sudipta K. Bera, Avinash Kumar, Souvik Sil +3
We trap absorbing micro-particles in air by photophoretic forces generated using a single loosely focused Gaussian trapping beam. We measure a component of the radial Brownian moti…
