Interferometric integrated planar Bragg filter for all- optical single-sideband suppression
نویسنده
چکیده
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 silica-on-silicon. Keywords-planar Bragg grating; photonic Hilbert transformer; single sideband suppression; direct UV writing

Phase controlled integrated interferometric single-sideband filter based on planar Bragg gratings implementing photonic Hilbert transform.
The monolithically integrated all-optical single-sideband (SSB) filter based on photonic Hilbert transform and planar Bragg gratings is proposed and experimentally demonstrated. An SSB suppression of 12 dB at 6 GHz and sideband switching are achieved via thermal tuning. An X-coupler, photonic Hilbert transformer, flat top reflector, and a micro heater are incorporated in a single silicon-on-sil...

Planar Bragg grating based photonic Hilbert transformers (PHTs) with THz bandwidths are proposed and practically demonstrated. An X-coupler, PHT, and a flat-top reflector are incorporated, demonstrating 2THz all-optical single-sideband filters. Devices are fabricated via a direct UV grating writing technique on a silica-on-silicon platform.
متن کاملDistributed Bragg grating integrated-optical filters: Synthesis and fabrication
The design, fabrication, and measurement of planar, passive Bragg grating-based transmission filters is presented. We combine interferometric lithography, spatial-phase-locked electron-beam lithography, x-ray nanolithography, and optical lithography with silica-on-silicon waveguiding substrates to define rib waveguides and grating patterns that have multiple quarter-wave shifts along the gratin...
متن کاملOptical single sideband signal generation relying on a single-drive Mach-Zehnder modulator for radio over fibre communications
Abstract: Optical single sideband (OSSB) signals are conventionally generated using a dual-drive Mach–Zehnder modulator (MZM) or by using a single-drive MZM in conjunction with a fibre Bragg grating filter. In this study, the authors propose and mathematically characterise a novel radio over fibre downlink in which an OSSB signal is generated using a single-drive, rather than dual-drive, MZM wi...

For receiving broadband satellite signal in airplanes, phased array antenna systems can be used instead of conventional satellite dishes, with advantages such as small weight and better aerodynamic performance. The corresponding beam forming and beam steering system can be implemented in the optical domain. The goal of this master assignment is to analyze and verify the functionality of an opti...
