چکیده
We propose the use of interleaved graphene sections on top of a silicon waveguide to implement tunable Bragg gratings. The filter central wavelength and bandwidth can be controlled changing the chemical potential of the graphene sections. Apodization techniques are also presented.

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...
متن کاملLaser erasable implanted gratings for integrated silicon photonics.
In this work we experimentally demonstrate laser erasable germanium implanted Bragg gratings in SOI. Bragg gratings are formed in a silicon waveguide by ion implantation induced amorphization, and are subsequently erased by a contained laser thermal treatment process. An extinction ratio up to 24dB has been demonstrated in transmission for the fabricated implanted Bragg gratings with lengths up...
متن کاملInterferometric integrated planar Bragg filter for all- optical single-sideband suppression
An integrated planar Bragg filter is proposed and experimentally demonstrated. X-couplers and Bragg gratings, operating as photonic Hilbert transformer and flat-top band gap reflectors, are incorporated. Optical signals reflected from these two gratings interference with each other are suitable for single sideband suppression. The device is fabricated by Direct UV grating writing technology in ...
متن کاملDesign, fabrication and measurement of integrated Bragg grating optical filters
The subject of this thesis is the design, analysis, fabrication, and characterization of integrated Bragg grating optical filters. We begin by describing the design and analysis of three essential building blocks needed for integrated Bragg grating filters: waveguides, directional couplers and Bragg gratings. Next, we describe and implement a flexible fabrication methodology for building integr...
متن کاملMultichannel Bragg gratings in silicon waveguides with asymmetric sidewall modulation.
We demonstrate a new type of on-chip Bragg grating designed to possess multiple stopbands at predetermined wavelengths. By employing sidewall modulation to control the full width half-maximum and extinction ratio, and through the incorporation of multiple spatial frequencies into the gratings' periodicities, we show that Bragg reflection can be achieved at particular wavelengths of interest wit...
