摘要

A tunable single-longitudinal-mode (SLM) fiber optical parametric oscillator (FOPO) is proposed and demonstratednexperimentally. A sub-ring cavity with a short cavity length is used to suppress the longitudinalnmodes and broaden the longitudinal mode spacing. A fiber loop mirror, consisted of an unpumped erbiumdopednfiber, acts as an autotracking filter for providing fine mode restriction and ensuring the singlefrequencynoperation. The measurement based on a homodyne method shows that the FOPO provides thenSLM output. Furthermore the SLM FOPO can be tunable over 14 nm for each of the signal and the idler,nwhich is limited only by the gain bandwidth of the fiber optical parametric amplifier. © 2010 Optical Societynof America
