Apodised Bragg gratings in planar waveguides for add-drop filters
We report on the fabrication by electron-beam lithography of Bragg gratings, which serve as wavelength-selective elements of a Mach–Zehnder-type add-drop filter. To meet telecommunication network requirements, the gratings must have about 20 000 lines, corresponding to a length on the order of 10 mm. Furthermore, the coupling strength of the gratings has to be varied according to a bell-shaped ...
متن کاملFirst- and Second-Order Bragg Gratings in Single-Mode Planar Waveguides of Chalcogenide Glasses
Firstand second-order Bragg reflectors at telecommunication wavelength (1.5 m) were fabricated in single-mode monolayer (As2S3) and multilayer (As-S-Se/As-S) chalcogenide glass (ChG) planar waveguides with near bandgap illumination using an interferometric technique. Reflectivities as high as 90% near 1555 nm, and index modulations up to 3 10 4 were achieved. The volume photodarkening effect is...
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 کاملIntegrated shadow mask for sampled Bragg gratings in chalcogenide (As(2)S(3)) planar waveguides.
We have developed a new approach for producing high performance sampled Bragg gratings in planar waveguides as a platform for WDM on-chip signal processing in a compact integrated device. Using this method we have successfully integrated a shadow mask directly onto a chalcogenide (As(2)S(3)) waveguide using standard semiconductor processing, eliminating misalignment errors between the mask and ...
متن کاملOptical Filters Utilizing Ion Implanted Bragg Gratings in SOI Waveguides
The refractive index modulation associated with the implantation of oxygen or silicon into waveguides formed in silicon-oninsulator (SOI) has been investigated to determine the feasibility of producing planar, implantation induced Bragg grating optical filters. A two-dimensional coupled mode theory-based simulation suggests that relatively short grating lengths, on the order of a thousand micro...
