High power PM fiber amplifier and broadband source

A polarization maintaining (PM) 1.5 /spl mu/m amplifier was demonstrated by externally inducing strain birefringence in a nominally non-polarization maintaining double cladding Er/Yb fiber. The 27 dBm amplifier had a 17 dB polarization extinction and was v-groove side-pumped by a broad stripe diode. A line broadband source is also demonstrated.
