Abstract
Organic nonlinear optical crystal 2-Adamanthylamino-5-nitropyridine (AANP) has attracted attention because of its large nonlinear susceptibility and the possibility of phase matching in the near-infrared wavelength region. To achieve high efficiency of propagation and modulation of light, it is necessary to fabricate optical waveguides of the crystal. Electron beam irradiation method is well known technique for polymer pattering in the order of nanometer. In this work we apply electron beam irradiation method to AANP single crystal to modulate refractive index of it and fabricated an optical waveguide.
