Nanophotonics . 2024 Dec; 11(4):847-854. PMID: 39635390
Numerous approaches have been developed to generate optical vortex beams carrying orbital angular momentum (OAM) over the past decades, but the direct intracavity generation of such beams with practical output...

Kelly T, Rikimi S, Davidson I, Chen Y, Bawn S, Bradley T, et al.
Opt Express . 2024 Jun; 32(12):20459-20470. PMID: 38859427
When a hollow core fiber is drawn, the core and cladding holes within the internal cane geometry are pressurized with an inert gas to enable precise control over the internal...

Taengnoi N, Bottrill K, Hong Y, Yu W, Sahu J, Hanzo L, et al.
Opt Express . 2024 Jun; 32(9):15483-15492. PMID: 38859197
We present wavelength-division multiplexed coherent transmission in an O-band amplified link enabled by bismuth-doped fiber amplifiers (BDFAs). Transmission of 4 × 25 GBd DP-16QAM (4 × 200 Gb/s) is demonstrated...

Lanari A, Mulvad H, Abokhamis Mousavi S, Davidson I, Fu Q, Horak P, et al.
Opt Express . 2023 Dec; 31(25):41191-41201. PMID: 38087524
We demonstrate a multi-watt, picosecond pulse duration laser source by exploiting a cascaded Raman process to the second Stokes signal at a wavelength of 2.58 μm in a methane-filled Nested...

Ji K, Davidson I, Sahu J, Richardson D, Wabnitz S, Guasoni M
Nat Commun . 2023 Nov; 14(1):7704. PMID: 38001059
Novel fundamental notions helping in the interpretation of the complex dynamics of nonlinear systems are essential to our understanding and ability to exploit them. In this work we predict and...

Opt Express . 2023 Oct; 31(21):34064-34073. PMID: 37859171
By exploiting the excellent short-term phase stability between consecutive pulses from a free-running optical parametric oscillator frequency comb, we report the first example of hollow-core fiber-delivered heterodyne spectroscopy in the...

FEMS Microbiol Lett . 2023 Aug; 370. PMID: 37573143
The soybean endosymbiont Bradyrhizobium diazoefficiens harbours the complete denitrification pathway that is catalysed by a periplasmic nitrate reductase (Nap), a copper (Cu)-containing nitrite reductase (NirK), a c-type nitric oxide reductase...
