Dispersion flattened extremely high-birefringent kagome lattice elliptic core photonic crystal fiber in THz regime
摘要： A highly birefringent elliptic porous-core photonic crystal fiber with kagome lattice cladding has been presented for terahertz (THz) wave transmission. The slotted airholes inside the elliptic core effectively disrupt the symmetry of the porous-core which offers extremely high modal birefringence whereas the kagome cladding structure results in significantly low effective material loss (EML). The birefringence of the proposed structure is 9.73 × 10?2 for y-polarized mode at an operating frequency of 1 THz. The suggested structure also provides very flat dispersion over a bandwidth of 300 GHz. It is highly expected that this elliptic core waveguide would be remarkably useful in numerous polarization maintaining THz applications.

[IEEE 2018 20th International Conference on Transparent Optical Networks (ICTON) - Bucharest (2018.7.1-2018.7.5)] 2018 20th International Conference on Transparent Optical Networks (ICTON) - Hollow Core Antiresonant Fibers: Novel Designs, Materials and Applications
摘要： The development of hollow core optical fibers (HCs) based on the antiresonant optical principle is gaining a significant interest within the optical fiber research community due, among others, to their broadband transmission, mid-infrared and ultra-violet operation, as well as their unique ability to handle high optical power. In this work, we offer an update on our recent activities related to the introduction of novel HCs designs, the fabrication of HCs based on composite materials and, in particular, to the development of novel HCs for mid- infrared transmission. These novel forms of optical fibers may unable a range of novel, still unexplored applications.

[IEEE 2019 21st International Conference on Transparent Optical Networks (ICTON) - Angers, France (2019.7.9-2019.7.13)] 2019 21st International Conference on Transparent Optical Networks (ICTON) - How to Amplify Light in an Unfilled Hollow Core Optical Fiber
摘要： Optical amplification in a hollow core fiber is typically realised by filling the fiber with a gas and exploiting its active properties. In contrast, here we explore the theoretical possibility of achieving light amplification in an unfilled hollow core antiresonant fiber. In order to do so, we propose and discuss a hollow fiber design based on a combination of resonant and anti-resonant elements within the cladding area.
