As quantum key distribution has reached the maturity level for practical deployment, questions about the co-integration with existing classical communication systems are of utmost importance. To th…
Unfortunately, we have made a mistake on the name of co-author and missed the DOI of our dataset. It would have no influence on any of our results, and the correct name and DOI are given here.
Light traversing an optical fiber is subject to various local phase perturbations driven by temperature. This thermal phase sensitivity is undesirable in fiber interferometers and their application…
Photothermal spectroscopy provides an attractive way of sensitive gas detection with a large dynamic range. Previous photothermal gas sensors normally use an optical interferometer for measuring th…
We study and demonstrate angle-cleaved fusion splicing between single mode fiber (SMF) and nested anti-resonant node-less fiber (NANF). First, we analyze the trade-off between the connection loss a…
Environmental temperature fluctuations cause phase changes of the light propagating through optical fibers due to their thermal sensitivity. This limits the stability of fiber delay-line interferom…
The feasibility of coexisting a quantum channel with carrier-grade classical optical channels over Hollow Core Nested Antiresonant Nodeless Fibre (HC-NANF) is experimentally explored for the first …
We present a study into the gas pressure and composition within a hollow core optical fiber immediately after fabrication. Results from three different experimental techniques indicate that the ini…
Coupled-mode theory is a powerful tool to understand and control the effects of deployment and fabrication imperfections on optical waveguides. Although it provides many advantages compared to the …
The loss of hollow-core Nested Antiresonant Nodeless Fiber (NANF) has been steadily decreasing lately, approaching that of standard Single-Mode Fiber (SMF). As for non-linear effects, they are alre…
