Dispersion correction of surface-normal optical interconnection using two compensated holograms
Performance of optical interconnects using volume holographic gratings and substrate-guided waves is subject to source wavelength detuning which originates from laser chirping and operating temperature changes. In this letter, we characterize and measure the dispersion of commonly used surface-normal volume holographic gratings. Dispersion characteristics of a 20 mm thick photopolymer volume ho...
متن کاملModeling and design of planar slanted volume holographic gratings for wavelength-division-multiplexing applications.
Holographic gratings are modeled and designed for path-reversed substrate-guided-wave wavelength-division demultiplexing (WDDM) as a continuation of earlier research [Appl. Opt. 38, 3046 (1999)]. An efficient and practical method is developed to simulate the slanted volume holographic gratings. The trade-off between dispersion and the bandwidth of the holograms is analyzed. A 60 degrees (incide...
متن کاملOptical 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...
متن کاملATLAS: a Cassegrain spectrograph based on volume phase holographic gratings
We are proposing a new spectrograph (ATLAS) which would revolutionise intermediate-dispersion observations at the AAT. Based on the new technology of Volume Phase Holographic gratings, and using transmission optics, ATLAS offers high throughput and a wide field (24′). It will be ideally suited to extensive surveys of faint objects. It has been designed with a collimated beam diameter of 150 mm,...
متن کاملOptimization of multiplexed holographic gratings in PQ-PMMA for spectral-spatial imaging filters.
Holographic gratings formed in thick phenanthrenquinone- (PQ-) doped poly(methyl methacrylate) (PMMA) can be made to have narrowband spectral and spatial transmittance filtering properties. We present the design and performance of angle-multiplexed holographic filters formed in PQ-PMMA at 488 nm and reconstructed with a LED operated at approximately 630 nm. The dark delay time between exposure ...
