    CO2 Laser Writing of Long-Period Fiber Gratings in Polarization-Maintaining Fiber under Tension

    We demonstrate CO2 laser writing of long-period fiber gratings (LPFGs) in a panda polarization-maintaining (PM) fiber under external tension. The transmission spectrum of the LPFGs depends on the irradiation dire...
