Title: PERFORMANCE TESTING DEVICE FOR MULTI-CHANNEL TUNABLE LASER
Abstract:
A performance testing device for a multi-channel tunable laser, comprising a collimating and coupling lens (3), a first light-beam splitter (4), a power testing unit (5), a side-mode suppression ratio testing unit (6), a wavelength testing unit (7) and a control and drive unit (8), wherein a reflection light path of the first light-beam splitter (4) is provided with the power testing unit (5), a transmission light path of the first light-beam splitter (4) is provided with the wavelength testing unit (7), a reflection light path of a second light-beam splitter (501) is provided with the side-mode suppression ratio testing unit (6), and the control and drive unit (8) is in a control connection with the power testing unit (5), the side-mode suppression ratio testing unit (6) and the wavelength testing unit (7). The performance testing device is simple in structure, low in cost, and convenient to use.
