Simultaneous measurement of multichannel laser linewidths and spacing by use of stimulated Brillouin scattering in optical fiber.
A novel method for measuring the linewidth of each laser and channel spacing in a multichannel transmission system is presented. Using the dependence of the Stokes frequency shift on the pump wavelength in stimulated Brillouin scattering, we are able to construct a delayed self-heterodyne interferometer that can measure the linewidths and channel spacing simultaneously.
