Wide angle and narrow-band asymmetric absorption in visible and near-infrared regime through lossy Bragg stacks

Absorber is an important component in various optical devices. Here we report a novel type of asymmetric absorber in the visible and near-infrared spectrum which is based on lossy Bragg stacks. The lossy Bragg stacks can achieve near-perfect absorption at one side and high reflection at the other within the narrow bands (several nm) of resonance wavelengths, whereas display almost identical abs...

Water vapor absorption of visible and near infrared radiation.

Water vapor error function absorption coefficients for visible and near ir radiation have been recalculated from experimental transmission data. The error function absorption coefficients and the resulting transmissions as a function of precipitable water vapor are tabulated for wavelengths from 0.2 micro to 1.3 micro. Comparisons are made between computed and measured spectral transmittances.

A modi"ed k-distribution approach applied to narrow band water vapour and oxygen absorption estimates in the near infrared

We apply a modi"ed version of the k-distribution method to derive expressions for the total and in-layer transmission of layered atmospheres in the H 2 O and O 2 absorption bands around 900 and 762 nm, respectively. The calculations are exemplary performed for the channels settings of the forthcoming Medium Resolution Imaging Spectrometer (MERIS), to be launched onboard ESA's Environmental Sate...

Polarization and incident angle insensitive germanium nano-pyramid array for perfect absorption in visible regime

An extraordinary light harvesting property of a periodic nano-pyramid array is reported. It is found that the nano-pyramid array can absorb light efficiently with an average absorptivity of 0.998 over the whole visible waveband. The ultra-high absorption is independent of the incoming light on polarization state and insensitive within a broad angle range. We attribute the efficient light harves...

Wide-angle near infrared polarizer with extremely high extinction ratio.

An infrared polarizer is designed with a predicted extremely high extinction ratio exceeding 3 × 10(16) and transmittance higher than 89% for one polarization in the wavelength region from 1.6 to 2.3 µm. Moreover, the performance does not start to deteriorate until 60° tilting angle. The wide-angle high transmission is attributed to the excitation of magnetic polaritons and suitable LC circuit ...
