Tóm tắt

In this paper, the authors present a review of enhancement and wavelength shift of abnormal up-conversion green light emission from erbium ions doped in silica with narrow line-width in the metallic-coated microsphere cavity. Although the phenomenon of the 537 nm- green light emission is not yet understood, its enhancement of several orders of magnitude seems to be due to the excitation of plasmon. The metallic-coated microsphere cavity has led to the lowest threshold so far observed in microsphere cavity lasers from 0.2 m W to 60 n W. By combining micro-cavity and surface plasmonic enhancement effect the researchers have created a new kind of photonic devices.
