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…
Measurement of probe displacement to the thermal resolution limit in photonic force microscopy using a miniature quadrant photodetector
Sambit Bikas Pal, Arijit Haldar, Basudev Roy +1
A photonic force microscope comprises of an optically trapped micro-probe and a position detection system to track the motion of the probe. Signal collection for motion detection i…
High-accuracy wavemeter based on a stabilized diode laser
Ayan Banerjee, Umakant D. Rapol, Ajay Wasan +1
We have built a high-accuracy wavelength meter for tunable lasers using a scanning Michelson interferometer and a reference laser of known wavelength. The reference laser is a freq…
