摘要

With the development of DWDM, optical analysers which are portable and can be applied to DWDM project site, are in great demand. This paper describes a novel method for wavelength fine-selection. This new method employs a refractive optical lever system, the structure of which is simple. It also has low cost and enough feasibility. This is a significant improvement not only on the wavelength discrimination capability of optical spectrum analysers for demanding DWDM test applications, but also on technology of frequency stabilization of lasers. We firstly demonstrate the refractive optical lever principle of a wedge prisms and the amplification factors for wedge prisms with different wedge angles. Secondly, the feasible experiment is done, the aim of which is improving the wavelength selecting accuracy of the optical spectrum analyser.
