Wavelet Image Processing Applied to Laser Beam Propagation in Polarized Optical Waveguides

摘要

Polarization in optical waveguides is always an aspect of optical loss and consequently impacts device performance. Wavelet image processing allows a means to detect optical signals buried under noise. Orthogonality is an essential element in wavelet bases. There are three primary types of multiresolution bases: orthogonal wavelet bases, semiorthogonal wavelet bases, and biorthog-onal wavelet bases. Wavelet image processing will be applied to laser beam propagation in lithium niobate and nonlinear polymer waveguides to achieve detection of signals below noise and a better understanding of polarization as an aspect of device performance.
