Sub-picosecond Graphene-based Harmonically Mode-Locked Fiber Laser With Repetition Rates up to 2.22 GHz

open access: yesEPJ Web of Conferences, 2013
Passive harmonic-mode locking (PHML) of erbium-doped fiber laser with multilayer graphene is presented. The laser could operate at several harmonics (from 2nd to 21st) of the fundamental repetition frequency of the ring resonator (106 MHz).

A Microwave Microfluidic Sensor Based on a Dual-Mode Resonator for Dual-Sensing Applications

open access: yesSensors, 2017
In this paper, we propose a novel microwave microfluidic sensor with dual-sensing capability. The sensor is based on a dual-mode resonator that consists of a folded microstrip line loaded with interdigital lines and a stub at the plane of symmetry.

Major reshaping of narrow beams by resonant multilayer structures

open access: yesOptics Express, 2020
Major reshaping of electromagnetic MM-wave beams transmitted at resonant frequencies through high-quality multilayer structures is demonstrated. Beam reshaping emerges due to efficient excitation of intrinsic quasi-optical modes with complex spatial profiles by an incident beam.
