Compact low energy fiber laser femtosecond deactivation of viral species

Vitor Marino Schneider, Florence Verrier, Meenal Soni, Shawn M. O’Malley

A compact 1550 nm low pulse energy erbium doped femtosecond fiber laser is used to inactivate viruses via Impulse Stimulated Raman Scattering (ISRS). Inactivation using this method was selective to the virus and not cells.

Arbitrary shaped microlens array laser sintered on glass sheets

Changyi Lai, Vitor Marino Schneider

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.

Analysis of distributed-feedback lasers with fractionally organized gratings

Haroldo T. Hattori, Vitor Marino Schneider, Carmem Lucia Barbosa

We analyze the performance of distributed-feedback lasers with special grating structures. These grating structures consist of subgratings with different lengths (that are integer multiples of a reference length) and/or different phase shifts (that are also integer multiples of a reference phase shift). …

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

Vitor Marino Schneider, James A. West, Karl W. Koch

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 [1].

Fast detection of single sided diffracted defects in display glass

Vitor Marino Schneider, Michal Mlejnek, Kevin T. Gahagan

A fast non-interferometric system for measurement of diffraction patterns based on the incidence of partially coherent light in display glass is assembled. The system provides an acceptable qualitative measurement for the detection of asymmetric defects.

Steady‐state analysis of a directional square lattice band‐edge photonic crystal lasers

Rogerio Moreira Cazo, Carmem Lucia Barbosa, Haroldo T. Hattori, Vitor Marino Schneider

Abstract The original square‐lattice band‐edge structure emitted light in different directions. In a recent paper [18], we have improved the directivity of these structures by using a honeycomb photonic crystal to shield the original structure. This has improved the performance of such …

Analysis of strategies to improve the directionality of square lattice band-edge photonic crystal structures

Haroldo T. Hattori, Vitor Marino Schneider, Rogerio Moreira Cazo, Carmem Lucia Barbosa

Recently, photonic crystal band-edge structures have been analyzed in the literature. However, most devices that have been presented so far emit light in different directions. We present a modal analysis (no gain included) of a few schemes to improve the directionality of …

Dispersion characteristics of segmented optical fibers

Vitor Marino Schneider, Haroldo T. Hattori

A direct scalar two-dimensional routine based on the method of lines is implemented to analyze the dispersion characteristics of segmented fibers. In this kind of structure, dispersion control in a simple profile is achieved by variations in the filling ratio of the …
