Arbitrary shaped microlens array laser sintered on glass sheets.

A new technique based on laser vitrification of cordierite ceramic powders is used to fabricate arbitrarily shaped microlens arrays on a glass substrate. Crack-free semispherical and quasi-spherical lenses with good optical and surface quality are demonstrated.

An E-field Eigenvalue Method for Computing Waveguides and Photonic Band-Gap Properties

A new direct vectorial two-dimensional solution based on an eigenvalue method is implemented to analyze waveguides and photonic band-gap structures based on a simpler E-field formulation unlike the H-field formulation.
