We present a theoretical study of a new application of the phase-shifted Bragg grating
(PSBG) as an optical spatial differentiator operating in reflection. We demonstrate that the …

Integrated Microwave photonics (IMWP) signal processing using Photonic Integrated
Circuits (PICs) has attracted a great deal of attention in recent years as an enabling …

All-optical spatial frequency filtering has a long history with many applications now
commonly replaced with digital alternatives. Although optical approaches are attractive in …

As a special kind of Bragg grating, phase-shifted fiber Bragg grating (PS-FBG) has attracted
extensive attention because of its extremely narrow transmission window and excellent …

A gas pressure sensor, based on a phase-shifted fiber Bragg grating (PS-FBG) modulated
by a hollow cavity, is proposed and demonstrated in this Letter. The device was fabricated …

In this paper, we propose and implement a wavelet-modified segmented phase-only filter for
in-plane rotated object recognition. The wavelet filter is combined with the segmented phase …

Показаны возможность увеличения разрешающей способности до 0,005 нм,
повышение чувствительности на 1–2 порядка и возможность значительного упрощения …

Photonic-assisted receivers for instantaneous microwave frequency measurement are
devices used to measure the instantaneous frequency and amplitude of one or more …

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 …
