Blue-light generation by quasi-phase-matched frequency doubling in thermally poled optical fibers.
Periodically patterned second-order nonlinearities are created in optical fibers by thermal poling in vacuo. Cw quasi-phase-matched frequency conversion to the blue is demonstrated. The measured bandwidth, 0.78 nm cm, is close to the theoretical prediction.
