Abstract

We propose and demonstrate a simple compact, inexpensive, SOA-based, multi-wavelength tunable (C- to L-band) fiber laser. A C-band design SOA is used, yet multi-wavelength operation either at the C or L-band region is accomplished by exploiting the gain compression phenomena of the SOA. We demonstrate that the wavelength tunability can be achieved either by inserting a variable attenuator inside the cavity of the laser or by changing the reflectivity of the mirrors. We exploit two different kinds of loop mirrors, a Sagnac and a Lyot-Sagnac loop mirror, which perform multiple functions. Stable multi-wavelength operation is achieved at room temperature without temperature compensation techniques, with measured power and the wavelength stability within < ±0.5 dB and ±0.1 nm, respectively.

用于光通信应用的可调谐多波长SOA线性腔光纤激光源
我们提出并演示了一种简单、紧凑、廉价、基于soa的多波长可调谐(C至l波段)光纤激光器。使用了C波段设计的SOA,但是在C或l波段区域的多波长操作是通过利用SOA的增益压缩现象来完成的。我们证明了波长可调性可以通过在激光器腔内插入可变衰减器或通过改变反射镜的反射率来实现。我们利用了两种不同类型的循环镜像,Sagnac和Lyot-Sagnac循环镜像,它们执行多种功能。在室温下实现稳定的多波长工作,无需温度补偿技术,测量功率和波长稳定性在<以内;±0.5 dB和±0.1 nm。
