Abstract :
A depolarized source is demonstrated at 1.3 μm by using a Ti:LiNbO3 phase modulator to modulate a diode-pumped Nd:YAG laser. This approach is shown to be simultaneously effective in increasing the threshold for stimulated Brillouin scattering (SBS). SBS was totally suppressed in 10.5 km fiber for fiber input powers up to 14.2 mW when the phase modulator was driven at 1 GHz. Stable operation was observed when the depolarized source was used as the input to a remote integrated optic modulator.
