Haptic Manipulation of Microspheres Using Optical Tweezers Under the Guidance of Artificial Force Fields
Ibrahim Bukusoglu, Cagatay Basdogan, Alper Kiraz +1
Using optical tweezers and a haptic device, microspheres having diameters ranging from 3 to 4 um (floating in a fluid solution) are manipulated in order to form patterns of coupled…
A method for volume stabilization of single, dye-doped water microdroplets with femtoliter resolution
A. Kiraz, A. Kurt, M. A. Dündar +2
A self-control mechanism that stabilizes the size of Rhodamine B-doped water microdroplets standing on a superhydrophobic surface is demonstrated. The mechanism relies on the inter…
Lasing from single, stationary, dye-doped glycerol/water microdroplets located on a superhydrophobic surface
A. Kiraz, A. Sennaroglu, S. Doğanay +4
We report laser emission from single, stationary, Rhodamine B-doped glycerol/water microdroplets located on a superhydrophobic surface. In the experiments, a pulsed, frequency-doub…
Propagation of Electromagnetic Waves in Linear Media and Pseudo-Hermiticity
Ali Mostafazadeh, Farhang Loran
We express the electromagnetic field propagating in an arbitrary time-independent non-dispersive medium in terms of an operator that turns out to be pseudo-Hermitian for Hermitian…
