We report an all-fiber polarization switch made out of silica-based microstructured fiber suitable for Q-switching all-fiber lasers. Nanosecond high-voltage pulses are used to heat and expand an internal electrode to cause λ 2 -polarization rotation in less than 10 ns for 1.5 μ m light. The 10 cm long component has an experimentally measured optical insertion loss of 0.2 dB and a 0 10 kHz repetition frequency capacity and has been durability tested for more than 10 9 pulses.
