A self-adaptive microwave photonic bandpass filter
(2019)
We present a microwave photonic self-adaptive bandpass filter that performs filtering on the instantaneous frequency of an unknown microwave signal. The filter maintains a bandpass characteristic around the carrier frequency ...
An Eigenanalysis Study of Tunable THz and Photonic Unbounded Structures Employing Finite Element Method
(2019)
This work aims at the establishment of a rigorous full-wave eigenmode analysis technique based on a finite element scheme for the study of terahertz (THz) or photonic/optical unbounded structures. This numerical tool follows ...
Hollow-core fiber with nested anti-resonant tubes for low-loss THz guidance
(2018)
A hollow-core fiber with nested anti-resonant node-free cladding tubes suitable for broadband THz guidance with low transmission losses is proposed. It is shown that the tube separation and tube thickness of the inner ...
Multi-core Fiber Based Mm-wave Generation, Radio-over-Fiber, and Power-over-Fiber
(2018)
We propose a multi-core fiber (MCFs) based concept which simultaneously use to generate millimeter wave (mm-wave) signal
Microwave Photonic Linear Frequency Networks
(2019)
We present the concept of microwave photonic linear frequency networks, in which a transfer function for the instantaneous frequency of band-limited microwave systems may be defined and synthesized with microwave photonic ...
Tunable THz Signal Generation and Radioover-Fiber Link based on an Optoelectronic Oscillator-driven Optical Frequency Comb
(2019)
We propose and demonstrate experimentally a photonic THz signal generation technique based on a tunable optoelectronic oscillator (OEO), and its application in a radio over fiber (RoF) link. The OEO's is tuned by varying ...

We propose and experimentally demonstrate a photonic THz signal generation technique combining a discrete optoelectronic oscillator (OEO) and optical frequency comb (OFC) generator. Using a microwave photonic filter (MPF), ...
Self-Oscillating Optical Frequency Comb: Application to Low Phase Noise Millimeter Wave Generation and Radio-Over-Fiber Link
(2018)
A self-oscillating optical frequency comb generator (SOFCG) is demonstrated by applying the optoelectronic loop feedback to an optical frequency comb generator (OFCG) based on a dual-drive Mach-Zehnder modulator. The ...
Optical frequency comb applied optoelectronic oscillator for millimeter-wave signal generation and its application
(International Society for Optics and Photonics, 2018)
Highly precise signal generation technique is a key for the realization of low-noise radar and ghost-less imaging in millimeter-wave bands. Current technologies based on an oven-controlled oscillator has a better phase ...
Design of PCB leaky-wave antennas for Wide angle beam steering
(2018)
A PCB based leaky-wave antenna (LWA) design for wide angle beam steering is presented. This design employs longitudinal slots inserted into a substrate-integrated waveguide for operation in the mm-wave V-band. It is optimized ...
