Tunable megawatt-scale sub-20 fs visible pulses from a fiber laser source
Mohammed Sabbah, Robbie Mears, Leah R. Murphy +4
Ultrafast laser pulses that are both tunable in wavelength and very short in duration are essential tools in fields ranging from biomedical imaging to ultrafast spectroscopy. While…
Highly multi-mode anti-resonant hollow core fibres
Robbie Mears, Kerrianne Harrington, William J Wadsworth +2
We report the characterisation of anti-resonant hollow core optical fibres guiding at least 50 spatial modes in the infrared. Their propagation losses were measured to be between 0…
Resonance-free deep ultraviolet to near infrared supercontinuum generation in a hollow-core antiresonant fibre
Mohammed Sabbah, Robbie Mears, Kerrianne Harrington +4
Supercontinuum generation in the ultraviolet spectral region is challenging in solid-core optical fibres due to solarization and photodarkening. Antiresonant hollow-core fibres hav…
Multi-core anti-resonant hollow core fibre
Robbie Mears, Kerrianne Harrington, William J Wadsworth +2
We report the fabrication and characterisation of a multi-core anti-resonant hollow core fibre with low inter-core coupling. The optical losses were 0.03 and 0.08 dB/m at 620 and 1…
Optical absorption spectrum reveals gaseous chlorine in anti-resonant hollow core fibres
Kerrianne Harrington, Robbie Mears, James M. Stone +3
We have observed unexpected spectral attenuation of ultraviolet light in freshly drawn hollow core optical fibres. When the fibre ends are left open to atmosphere, this loss featur…
Low-loss, compact, fibre-integrated cell for quantum memories
Cameron McGarry, Kerrianne Harrington, Daniel J. Goodwin +4
We present a low-loss, compact, hollow core optical fibre (HCF) cell integrated with single mode fibre (SMF). The cell is designed to be filled with atomic vapour and used as a com…
Guidance of ultraviolet light down to 190 nm in a hollow-core optical fibre
Robbie Mears, Kerrianne Harrington, William J. Wadsworth +3
We report an anti-resonant hollow core fibre with ultraviolet transmission down to 190 nm, covering the entire UV-A, UV-B and much of the UV-C band. Guidance from 190 - 400 nm is a…
Controlling and scripting laboratory hardware with open-source, intuitive interfaces: OpenFlexure Voice Control and OpenFlexure Blockly
Samuel McDermott, Richard Bowman, Kerrianne Harrington +2
Making user interaction with laboratory equipment more convenient and intuitive should promote experimental work and help researchers to complete their tasks efficiently. The most…
All-fibre wavefront sensor
Thomas A. Wright, Stephanos Yerolatsitis, Kerrianne Harrington +2
We report on a tapered three-core optical fibre that can be used as a tip-tilt wavefront sensor. In this device, a coupled region of a few millimetres at the sensing tip of the fib…
DV-QKD Coexistence With 1.6 Tbps Classical Channels Over Hollow Core Fibre
Obada Alia, Rodrigo S Tessinari, Sima Bahrani +11
The feasibility of coexisting a quantum channel with carrier-grade classical optical channels over Hollow Core Nested Antiresonant Nodeless Fibre (HC-NANF) is experimentally explor…
1.6 Tbps Classical Channel Coexistence With DV-QKD Over Hollow Core Nested Antiresonant Nodeless Fibre (HC-NANF)
O. Alia, R. S. Tessinari, T. D. Bradley +10
We demonstrate for the first time the coexistence of a quantum-channel and 8x200 Gpbs 16-QAM optical channels with launching powers as high as -9dBm per channel in a 2 km HC-NANF.…
Focal-ratio-degradation (FRD) mitigation in a multimode fiber link using mode-selective photonic lanterns
Aurélien Benoît, Stephanos Yerolatsitis, Kerrianne Harrington +2
We present a new way to mitigate focal-ratio degradation (FRD) when using optical fibers to transport multimode light. Our approach exploits a custom multicore fiber (MCF) with six…
The OpenFlexure Block Stage: Sub-100 nm fibre alignment with a monolithic plastic flexure stage
Qingxin Meng, Kerrianne Harrington, Julian Stirling +1
As 3D printers become more widely available, researchers are able to rapidly produce components that may have previously taken weeks to have machined. The resulting plastic compone…
High fidelity fibre-based physiological sensing deep in tissue
Tushar R. Choudhary, Michael G. Tanner, Alicia Megia-Fernandez +13
Physiological sensing deep in tissue, remains a clinical challenge. Here a flexible miniaturised sensing optrode providing a platform to perform minimally invasive in vivo in situ…
