Abstract
A performance testing device for a multi-channel tunable laser, comprising a collimating and coupling lens, a first beam splitter, a power testing unit, a side-mode suppression ratio testing unit, a wavelength testing unit and a control and drive unit, the power testing unit being positioned in a reflection path of the first beam splitter, the wavelength testing unit being positioned in a transmission path of the first beam splitter, the side-mode suppression ratio testing unit being positioned in a reflection path of the second beam splitter, the control and drive unit being in a control connection with the power testing unit, the side-mode suppression ratio testing unit and the wavelength testing unit. The performance testing device has a simple structure, a low cost, and is convenient to use.
