Description

The Agilent 11980A is a Mach-Zehnder interferometer of fixed delay. Used with an Agilent 71400 series or Agilent 83810B lightwave signal analyzer, it allows you to measure chirp and frequency modulation (FM) on DFB lasers. Traditional measurements of laser linewidth on single-line lasers can also be made.

The Agilent 11980A splits the optical energy into two paths, delaying one path with respect to the other, and recombines them in a second optical coupler. A polarization adjustment helps align the optical fields for maximum interference.

Together the interferometer, lightwave signal analyzer, and a gateable RF source permit the display of a true power spectrum of single-frequency lasers. This includes the display of intensity modulation linewidth and components of chirp caused by the intensity modulation.

Option 005 replaces the standard 0.76 km of delay with 5.2 km to measure laser linewidth down to 30 kHz.
