An erbium-doped-fiber-ring laser (EDFL) with more than 50 nm of continuous
wavelength tuning was achieved and analyzed through a numerical approach. A
n angle-tuned Fabry-Perot etalon was incorporated in the laser cavity as th
e wavelength-selective element. The numerical values are in close agreement
with the experimental results. (C) 2001 John Wiley & Sons, Inc.
