Abstract

In this letter, L‐band multiwavelength operation in an erbium‐doped fiber ring laser (EDFRL) is achieved by using a tunable Fabry–Perot etalon as the intracavity comb filter. It is found that, for a ring cavity, the gain spectrum can be controlled, and the flattened gain spectrum at the threshold can be obtained by optimizing the cavity Q‐factor. A maximum of six stable lines with a spacing of 1.3 nm in the wavelength range near 1590 nm has been produced at room temperature. © 2002 John Wiley & Sons, Inc.

A short wavelength band erbium-doped fiber laser (S-band EDFL) is demonstrated utilizing a fiber Bragg grating (FBG) in unidirectional ring configuration. The amplification in S-band is achieved using an erbium-doped fiber with depressed cladding, which suppressed gains at longer wavelength. The las
