Abstract

In this paper we demonstrate the use of a tunable laser source with strongly reduced source spontaneous emission (SSE) when applied to critical DWDM-components. The low SSE is a result of a new cavity design for tunable lasers. This design enables measurements of passive DWDM components with highest dynamic range. Enhancing common arrangements, a wavelength selective element (e.g. an OSA) can be replaced by a broadband receiver, a power meter. We will discuss principles and limitations of the arrangement and present experimental results. As test devices we used a Fiber Bragg Grating and a 16-channel Demultiplexer.
