Journal ArticleDOI
Ultracompact and low-power optical switch based on silicon photonic crystals
TL;DR: A slow-light-enhanced optical switch that is 36 times shorter than a conventional device for the same refractive index change and has a switching length of 5.2 microm is presented.
Journal ArticleDOI
Dispersion engineered slow light in photonic crystals: A comparison
Sebastian A. Schulz,Liam O'Faolain,Daryl M. Beggs,Thomas P. White,Andrea Melloni,Thomas F. Krauss +5 more
TL;DR: In this article, different types of dispersion engineered photonic crystal waveguides have been developed for slow light applications, and the group index bandwidth product (GBP) and the loss per delay in terms of dB ns −1 were compared.
Proceedings ArticleDOI

TL;DR: In this article, an integrated waveguide approach to photonic quantum circuits for high performance, miniaturization and scalability is presented. But the authors do not address the challenges of scaling up quantum circuits using new insights into how controlled operations can be efficiently realized.
Journal ArticleDOI
Loss engineered slow light waveguides
Liam O'Faolain,Sebastian A. Schulz,Daryl M. Beggs,Thomas P. White,Marko Spasenović,Laurens Kuipers,Francesco Morichetti,Andrea Melloni,Simon Mazoyer,Jean-Paul Hugonin,Philippe Lalanne,Thomas F. Krauss +11 more
TL;DR: A theoretical model is developed that accurately describes the loss spectra of PhC waveguides and reveals that the entire hole contributes coherently to the scattering process, in contrast to previous models that added up the scattering from short sections incoherently.
Journal ArticleDOI
Polarization Engineering in Photonic Crystal Waveguides for Spin-Photon Entanglers.

TL;DR: It is demonstrated that the light-matter interaction can be asymmetric, leading to unidirectional emission and a deterministic entangled photon source, and understanding the phase associated with both the LDOS and the QD spin is essential for a range of devices that can be realized with a QD in a PCW.
