Wavelength demultiplexing by chirped waveguide gratings

The performance of a chirped waveguide grating as a wavelength demultiplexer has been investigated. Considerations include TE-‘LX, TE-TM and TM-TM mode coupling for different incident angles and waveguide parameters. The spectral response of the chirped sinusoidal surface relief grating in the optical waveguide has been studied by means of Local Normal Mode Expansion (LNME) theory to account fo...

Analysis of diffraction by surface-relief crossed gratings with use of the Chandezon method: application to multilayer crossed gratings

A new formulation of the Chandezon method for crossed gratings is presented. In the nonorthogonal translation coordinate system, an arbitrary field in a homogeneous source-free region can be expressed as the sum of a TE field and a TM field. It is shown that the whole solution can be derived from the eigensolutions of an operator independent of the polarization. In addition, use is made of the ...

Optical pulse compression based on nonlinear silicon waveguides and chirped Bragg gratings

Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...

Subwavelength surface-relief gratings for stellar coronagraphy.

We present a new design of a phase mask coronagraph implemented with subwavelength diffractive optical elements consisting of optimized surface-relief gratings. Phase mask coronagraphy is a recent technique that seeks to accommodate both high dynamic and high angular resolution imaging of faint sources around bright astrophysical objects such as exoplanets orbiting their host stars. The origina...

Plasmonic waves allow perfect transmission through sub-wavelength metallic gratings

We investigate the transmission properties of a metallic layer with narrow slits. Recent measurements and numerical calculations concerning the light transmission through metallic subwavelength structures suggest that an unexpectedly high transmission coefficient is possible. We analyze the time harmonic Maxwell’s equations in the H-parallel case for a fixed incident wavelength. Denoting by η >...
