As a new degree of freedom for optical manipulation, recently, spatiotemporal optical
vortices (STOVs) carrying transverse orbital angular momentums have been experimentally …

Integrated microwave photonics is an emerging field in which photonic integrated
technologies are employed to realize on-chip integration of microwave photonic systems …

Fiber Bragg gratings have been invented for over three decades now and have been
intensively employed in optical communication and sensor systems. The key limitation of a …

This paper presents the design and comprehensive analysis of an ultra-fast fractional-order
temporal differentiator (DIFF) based on a plasmonic inner-wall Bragg grating microring …

We experimentally demonstrate a terahertz-bandwidth photonic differentiator employing a
silicon-on-insulator directional coupler. The integrated waveguide coupler with two identical …

Design of a fractional-order photonic temporal differentiator, based on the silicon hybrid
plasmonic add-drop microring resonators, is proposed. Because of the strong light …

We propose an integrated Bragg grating (BG) filter with reflection light dropped in a silicon-
on-insulator platform. Most of the light reflected by the BG is coupled to a branch waveguide …

We report on the characterization of a photonic integrated circuit (PIC) for the generation of a
RF carrier in the millimeter-wave band up to the sub-THz region. The circuit is implemented …

A phase-shifted eccentric core fiber Bragg grating (PS-ECFBG) fabricated by electric arc
discharge (EAD) is presented and demonstrated. It is composed of a fraction of eccentric …

Microring-based photonic fractional differentiators play an important role in the on-chip all-
optical signal processing. Unfortunately, the previous works do not consider the time …
