| Abstract(in English) | The second-order nonlinearity of optical fiber is expected for applications to second-harmonic generators, optical modulators, or switches. We studied the second-order nonlinearity of silica fiber having side tunnels induced by poling with electrode wires put into the tunnels. Q-switched Nd: YAG laser pulses were coupled to the core of the fiber, and the second-harmonic wave was measured. To satisfy the phase matching condition, the quasi phase matching was performed by periodic erasure of nonlinearity. The poled fiber was irradiated with a KrF excimer laser through a silica mask patterned with a 40-μm pitch chromium stripe. By changing the angle of the fiber with respect to the mask pattern the optimum period was found to be 41.1μm, then the second-harmonic power increased by a factor of up to 15. |
