Sayson N, Pham H, Webb K, Ng V, Trainor L, Schwefel H, et al.
Opt Lett . 2018 Aug; 43(17):4180-4183. PMID: 30160746
Recent experiments have demonstrated the generation of widely spaced parametric sidebands that can evolve into "clustered" optical frequency combs in Kerr microresonators. Here we describe the physics that underpins the...

Sayson N, Webb K, Coen S, Erkintalo M, Murdoch S
Opt Lett . 2017 Dec; 42(24):5190-5193. PMID: 29240179
We report on the first experimental demonstration of widely tunable parametric sideband generation in a Kerr microresonator. Specifically, by pumping a silica microsphere in the normal dispersion regime, we achieve...

Webb K, Erkintalo M, Coen S, Murdoch S
Opt Lett . 2016 Dec; 41(20):4613-4616. PMID: 28005849
We report on the experimental observation of coherent cavity soliton frequency combs in silica microspheres. Specifically, we demonstrate that careful alignment of the microsphere relative to the coupling fiber taper...

Webb K, Erkintalo M, Xu Y, Broderick N, Dudley J, Genty G, et al.
Nat Commun . 2014 Sep; 5:4969. PMID: 25230247
The nonlinear interaction of light in an optical fibre can mimic the physics at an event horizon. This analogue arises when a weak probe wave is unable to pass through...

Ireland H, Miller G, Webb K, Cooper J, Humphries S
Thromb Haemost . 2004 Nov; 92(5):986-92. PMID: 15543324
A previous study had shown a strong relationship between a variant in factor VII activating protease (FSAP G511E) and advanced carotid atheroma. In-vitro, the variant has reduced fibrinolytic but normal...

Elrayess M, Webb K, Bellingan G, Whittall R, Kabir J, Hawe E, et al.
Atherosclerosis . 2004 Oct; 177(1):127-35. PMID: 15488875
The 643R allele of R643G polymorphism (also known as R670G in the premature protein) in PECAM-1 has been associated with risk of myocardial infarction (MI), while the 643G allele has...

Webb K, Martin J, Cotton J, Erusalimsky J, Humphries S
Exp Hematol . 2003 Jun; 31(6):488-94. PMID: 12829024
Objective: A common variant in intron 5 of the thrombopoietin (TPO) gene (4830C>A) has been associated with risk of myocardial infarction (MI). To explore the molecular mechanism of this association,...

Atherosclerosis . 2003 May; 168(1):131-8. PMID: 12732396
A 53G>A polymorphism identified in the 5' untranslated region (5'UTR) of the platelet endothelial cell adhesion molecule-1 (PECAM-1) gene alters a putative shear stress responsive element (SSRE). PECAM-1 was shown...
