Background Hong Kong has a high burden of influenza hospitalisation. This study estimated influenza vaccine effectiveness in hospitalised Hong Kong children aged 6 months to below 6 years using data potentially obtainable from routine surveillance so

We show numerically that a Kerr nonlinear system composed of two channel waveguides coupled periodically by circular microresonators can be used as an all optical diode. The diode has low intensity requirements ( ∼ 50 MW/cm 2 ) and compact dimensio

We show that the optical response of two channel waveguides coupled by a microresonator is well described by a Lorentzian model. Using this model we derive a set of coupled differential equations that describe Kerr nonlinear optical pulse propagation

Planar broad-area single-mode lasers, with modal widths of the order of tens of microns, are technologically important for high-power applications and improved coupling efficiency into optical fibers. They may also find new areas of applications in o

We analyze side-coupled standing-wave cavity structures consisting of Fabry-Perot and photonic crystal resonators coupled to two waveguides. We show that optical bright and dark states, analogous to those observed in coherent light-matter interaction

We propose and demonstrate electrically pumped, edge-emitting, large-area photonic crystal lasers. Effective index-guided and Bragg-guided lasing modes are obtained depending on the design of photonic crystal and facets.

Second order nonlinear effects, such as second harmonic generation and parametric amplification, can be dramatically enhanced in microring resonator structures. The quasi-phase-matching is achieved based on the position dependence of polarization ins

We consider finite-size effects in coupled cavity structures. Starting with microring resonator structures well described by transfer matrices, we obtain conditions that lead to the minimization of finite-size effects. Our approach does not require n
