Greater than 20%-efficient frequency doubling of 1532 nm nanosecond pulses in quasi-phase-matched germanosilicate optical fibers

Greater than 20%-efficient frequency doubling of 1532 nm nanosecond pulses in quasi-phase-matched germanosilicate optical fibers

We fabricated second-order nonlinear gratings in D-shaped germanosilicate fibres using thermal poling and periodic electrodes defined by standard photolithography. These gratings, up to 75mm long, have been used for efficient quasi-phase-matched frequency doubling of 1.532µm nanosecond pulses from a...
