Abstract/OtherAbstract:
Wavelength tunability of lasers is one of the most important parameters for achieving practical applications such as optical communication, environmental monitoring, and spectroscopy analysis. A wide-wavelength tunable laser is demonstrated on a single non-doped CdSe nanowire (NW) without changing pumping intensity and position, but by simply gradually cutting the NW shorter instead. The corresponding mechanism for the large wavelength shifts is determined as the absorption-emission-absorption (AEA) process in polar CdSe NWs.
