Abstract
In one embodiment this invention provides an integrated optical parametric amplifier device with an organic waveguiding matrix which exhibits second order nonlinear response, and which has a spatial periodic structure for quasi-phase matching of propagating waves. In a preferred type of device the waveguiding matrix has a two-dimensional channel configuration, and the matrix surfaces are in contact with organic cladding layers which exhibit second order nonlinear optical response and which have a lower index of refraction than the channel waveguiding medium.
