Telecom-band lasing characterization.

Caption

Telecom-band lasing characterization. (a) Emission spectra at different pump fluences of a single standing NW. Inset shows the corresponding normalized spectral intensity map. (b) Telecom-band lasing spectra from NWs with different indium compositions in the QWs at room temperature under a pump fluence of 1.3 Pth. (c-e) Optical images from the NW array before (c), and after (d) lasing threshold. (e) Image on (d) under an attenuated pump fluence.
