Abstract

A widely tunable erbium-doped all-fiber laser has been demonstrated. The tunable mechanism is based on a novel tunable filter using multimode interference effects (MMI). The tunable MMI filter was applied to fabricate a tunable erbium-doped fiber laser via a standard ring cavity. A tuning range of 60 nm was obtained, ranging from 1549 nm to 1609 nm, with a signal to noise ratio of 40 dB. The tunable MMI filter mechanism is very simple and inexpensive, but also quite efficient as a wavelength tunable filter.

摘要

已展示出一种广泛可调谐的掺铒全光纤激光器。可调谐机制基于一种利用多模干涉效应（MMI）的新型可调谐滤波器。该可调谐MMI滤波器通过标准环形腔被应用于制造可调谐掺铒光纤激光器。获得了60nm的调谐范围，从1549nm至1609nm，信噪比为40dB。该可调谐MMI滤波器机制非常简单且成本低廉，作为波长可调谐滤波器也相当高效。
