LaGuerre–Gaussian Emission Properties of Photonic Quantum Ring Hole-Type Lasers

Abstract

We report on the observation of LaGuerre-Gaussian (LG) beam profiles of photonic quantum ring (PQR) hole-type lasers. Naturally formed LG beams are highly valuable for optical tweezering applications, like transporting or manipulating DNA molecules. Various devices with different injection currents and hole diameters have been analyzed.Index Terms-LaGuerre-Gaussian, optical trapping, optical tweezers, photonic quantum ring, PQR hole-type lase.
