Abstract

A superfluorescent source used for scanning near-field optical microscope (SNOM) has been developed in this paper. The superfluorescent source originates from an amplified spontaneous emission (ASE) produced by an Er-doped fiber, with a relatively wide spectrum from 1531 nm to 1537 nm. This kind of superfluorescent fiber probe has relatively high photon flux over an ordinary probe. Different image qualities are obtained by the SNOM system with the superfluorescent source and the laser source respectively. Experimental result shows that the coherent noise of the SNOM image is dramatically reduced with the superfluorescent source.
