Abstract

We demonstrated a pigtailed nanoribbonring laser constructed with a 600 nm wide and 330 nm thick CdSnanoribbon. When the 20 - μ m -diameter ring was irradiated by light from a supercontinuum source, multi longitudinal mode laser emission was observed around 523.5 nm with full widths at half maximum of 0.27 nm. The laser output from the pigtail showed strong orientation-dependent polarization, with a maximum polarization ratio of 5 and power up to 3.7 nW.

Abstract

We demonstrate a freestanding nanowire ring laser, assembled by splicing the two ends of a CdS nanowire via a dissolved polymer nanowire. With ring diameter of less than 50 μm, the free-standing nanowire ring laser shows low lasing threshold, high robustness, and excellent mechanical flexibility. Also, the nanowire ring laser works well in liquid environment, showing the possibility of integrating the nano-ring laser into an optofluidic system. [ABSTRACT FROM AUTHOR]
