摘要：

In this letter, we describe a new discretely wavelength-selectable 1.5-mum source based on the use of a fiber Sagnac loop filter leading to the possibility of an efficient all-fiber source. The filter has an similar to1.6-dB insertion loss, 14-dB peak-to-valley transmission ratios, and can be tuned to a very precise match with the International Telecommunications Union-wavelength-division-multiplexing grid. We demonstrate 25-channel outputs with precise 50-GHz channel spacings and very large (65 dB) output signal to background noise ratios.
