Webb16 sep. 2015 · Figure 1a presents the schematic of the metallic-dielectric hybrid film-coated FP nanolaser. The device is composed of the main components of naturally doped n-type vertically aligned ZnO NWs array, ... Lasing in metallic-coated nanocavities. Nat. Photon. 1, 589–594 (2007) WebbHere we report for the first time laser operation in an electrically pumped metallic-coated nano-cavity formed by a semiconductor hetero-structure encapsulated in a thin gold film. The demonstrated lasers show a low threshold current and their dimensions are smaller than the smallest electrically pumped lasers reported so far.
