Optical Path, Wavelength and Power Monitoring Technique Using Frequency-Modulated Pilot Tones

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate a simple technique to monitor the optical paths, wavelengths, and powers of WDM signals using frequency-modulated (FM) pilot tones. Unlike the previously proposed monitoring technique using amplitude-modulated (AM) pilot tones, the proposed technique does not suffer from the cross-gain modulation and stimulated Raman scattering.
