Nonlinear Optical Waveguide Using Polymer Film Doped With 2-methyl-4-nitroaniline

Nonlinear optical devices based on integrated optics or guided-wave technology are very attractive because of their advantages such as phase matching by means of mode dispersion and large light intensity due to small cross-section of waveguides. Although certain organic materials have large nonlinear optical susceptibilities, organic crystals are too fragile to make a waveguide. On the other hand, poled polymer films, which can be coated and patterned photolithographically, are useful material to make guided-wave devices.
