Low polarization dependent diffraction grating for wavelength demultimlexing.
Popov, E; Hoose, J; Frankel, B; Keast, C; Fritze, M; Fan, T; Yost, D; Rabe, S.

ABSTRACT

A low polarization dependent, high diffraction efficiency grating for wavelength demultiplexer is proposed, manufactured by standard crystallographic etching of Si surface. Light is incident and diffracted inside the wafer, which is covered with reflecting metal. Optimized groove form results in a flat spectral response for TE and TM polarizations.

Laser-fabricated glass microlens arrays.

ABSTRACT

We report the fabrication of large, laser-formed refractive microlens arrays on doped borosilicate glass. Tuning the laser heat-source properties was found to give precise control over the melt process and the resulting lenslet geometries. Measurements of focal length, index, and surface shapes show excellent uniformity across these arrays.
