Abstract :
We demonstrated a pigtailed nanoribbon ring laser constructed with a 400 nm wide and 230 nm thick CdSe nanoribbon. When the 9-μm-diameter ring was irradiated by light from a semiconductor laser (532 nm, 10 ns, 10 Hz) laser, multi longitudinal mode laser emission was observed around 728 nm. The laser output from the pigtail showed strong orientation-dependent polarization, with a maximum polarization ratio of 5.
