چکیده
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.

Terahertz bandwidth photonic Hilbert transformers based on synthesized planar Bragg grating fabrication.
Terahertz bandwidth photonic Hilbert transformers are proposed and experimentally demonstrated. The integrated device is fabricated via a direct UV grating writing technique in a silica-on-silicon platform. The photonic Hilbert transformer operates at bandwidths of up to 2 THz (~16 nm) in the telecom band, a 10-fold greater bandwidth than any previously reported experimental approaches. Achievi...
متن کاملTunable Wideband Graphene based Filters in THz Band
In this paper, a procedure for analyzing and designing of tunable wideband band-pass and band-stop graphene based filters in the terahertz band is proposed. These planar wideband plasmonic filters are unique in their kind. With this procedure, it is possible to design filters with the desired functional characteristics in the form of the similar quarter-wavelength resonance stubs. The discontin...
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 کاملUltra-wideband microwave photonic phase shifter with a 360° tunable phase shift based on an erbium-ytterbium co-doped linearly chirped FBG.
A simple photonic approach to implementing an ultra-wideband microwave phase shifter based on an erbium-ytterbium (Er/Yb) co-doped linearly chirped fiber Bragg grating (LCFBG) is proposed and experimentally demonstrated. The LCFBG is designed to have a constant magnitude response over a reflection band, and a phase response that is linear and nonlinear in two sections in the reflection band. Wh...

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...
