Wood's anomalies and spectral uniformity of focusing diffractive optical elements
We report on simulations and measurements of focusing diffractive optical elements, fabricated as two-level binary optics. The diffractive optical elements are designed to separate and focus four specific wavelengths in the infrared. The simulations are based on a local linear grating model, and pre...

Spectral uniformity of two- and four-level diffractive optical elements for spectroscopy
We present simulations and characterization of gold coated diffractive optical elements (DOEs) that have been designed and fabricated in silicon for an industrial application of near-infrared spectroscopy. The DOE design is focusing and reflecting, and two-level and four-level binary designs were st...
Spectral uniformity of diffractive optical elements for spectroscopy
Characterization and polarization resolved simulation of diffractive optical elements
We present our activity on the characterization and simulation of diffractive optical elements (DOEs) for near infrared spectroscopy. The DOE surface is designed to direct and focus light of a limited set of wavelengths onto a detector. In order to perform this, the surface pattern has a complicated...
