Dispersion-tailored few-mode fiber design for tunable microwave photonic signal processing

Nazemosadat-Arsanjani, Seyedeh Bentolhoda; Gasulla Mestre, Ivana (The Optical Society, 2020-11-23)

[EN] We present a novel double-clad step-index few-mode fiber that operates as a five-sampled tunable true-time delay line. The unique feature of this design lies in its particular modal chromatic dispersion behavior, which ...
Heterogeneous multicore fiber-based microwave frequency measurement

Nazemosadat, Elham; García-Cortijo, Sergi; Gasulla Mestre, Ivana (The Optical Society, 2022-07-18)

[EN] A novel microwave frequency measurement scheme using a heterogeneous multicore fiber (MCF) is experimentally demonstrated. The inherently different relative group delays among the cores of a heterogeneous 7-core MCF ...
Mode-division multiplexing for microwave signal processing

Nazemosadat-Arsanjani, Seyedeh Bentolhoda; Gasulla Mestre, Ivana (IEEE, 2021-07-21)

[EN] We present an overview of different mode-division multiplexing fiber technologies engineered to provide tunable microwave signal processing, including signal filtering and optical beamforming for phased-array antennas. ...
Phased Array Antenna Beam-Steering in a Dispersion-Engineered Few-Mode Fiber

Nazemosadat, Elham; Herranz Herruzo, José Ignacio; Gasulla Mestre, Ivana (Institute of Electrical and Electronics Engineers, 2023-11-01)

[EN] We present, for the first time to our knowledge, experimental demonstration of tunable optical beamforming for phased array antennas using a few-mode fiber. The double-clad step-index few-mode fiber is dispersion ...
Reconfigurable Few-Mode Fiber-Based Microwave Photonic Filter

Nazemosadat, Elham; Gasulla Mestre, Ivana (Institute of Electrical and Electronics Engineers, 2022-10-01)

[EN] We experimentally demonstrate, for the first-time to our knowledge, tunable true-time delay line operation over a few-mode fiber link, in which the time delay can be continuously and widely tuned, from 46.3 to 105.6 ...
Tunable True-Time Delay Operation in A Dispersion-Engineered Few-Mode Fiber

Nazemosadat-Arsanjani, Seyedeh Bentolhoda; Gasulla Mestre, Ivana (IEEE, 2020-11-26)

[EN] We present a simple few-mode fiber design as a promising platform to implement tunable sampled true-time delay lines for radiofrequency signal processing. To the best of our knowledge, this is the first few-mode fiber ...
