Varied line spacing plane holographic grating recorded by using uniform line spacing plane gratings.
Uniform line spacing plane gratings are introduced into a recording system to generate aspherical wavefronts for recording varied line spacing plane holographic gratings. Analytical expressions of groove parameters are derived to the fourth order. A ray-tracing validation algorithm is provided based on Fermat's principle and a local search method. The recording parameters are optimized to recor...
متن کاملNumerical optimization of spherical variable-line-spacing grating X-ray spectrometers
Operation of an X-ray spectrometer based on a spherical variable-line-spacing (VLS) grating is analyzed using dedicated ray-tracing software allowing fast optimization of the grating parameters and spectrometer geometry. The analysis is illustrated with optical design of a model spectrometer to deliver a resolving power above 20400 at a photon energy of 930 eV (Cu L-edge). With this energy take...
متن کاملDirect Fabrication of Planar Grating by Ultrafast Laser Beam
Femtosecond laser pulse has been used for the machining of the gratings primarily due to its superior advantages over conventional continuous wave (CW) and long pulse lasers for micromachining. In this paper, we develop a novel technique for the fabrication of planar gratings by colliding two beams to generate interference fringes. This technique is simple, fast and low cost. We have successful...
متن کاملFabrication techniques for grating-based optical devices
We describe a novel, versatile process for fabricating integrated Bragg-grating devices. Our process addresses many of the critical challenges presented by such devices, including period selection, alignment, spatial coherence, and nanolithography. Using a combination of e-beam, x-ray, optical, and interference lithographies, we have successfully employed this process to construct 244 nm period...
متن کامل20GHz Channel Spacing InP-based Arrayed Waveguide Grating
We demonstrate a 10-channel InP-based Arrayed-Waveguide Grating (dimensions = 5.0x6.0 mm) with a 20-GHz channel spacing. The excess loss of the AWG is 5.5-6.3 dB, and the crosstalk level is below -15 dB. Introduction Arrayed waveguide Gratings (AWGs) are one of the key components for wavelength division multiplexing (WDM) applications, and narrowchannel-spacing AWG multi/demultiplexers are indi...
