TL;DR: The procedure aims to maximize the group index - bandwidth product by changing the position of the first two rows of holes of W1 line defect photonic crystal waveguides to achieve nearly constant group index- bandwidth product for group indices of 30-90.

TL;DR: The generation of correlated photon pairs in the telecom C-band at room temperature from a dispersion-engineered silicon photonic crystal waveguide paves the way toward scalable quantum information processing realized on-chip.

TL;DR: The results, supported by numerical simulations, emphasize the importance of engineering the dispersion of PhC waveguides to exploit the slow light enhancement of FWM efficiency, even for short device lengths.

TL;DR: In this article, a supercell geometry is proposed to suppress the low orders that do not couple into the quasiguided modes of the thin-film solar cell, which can tailor the strength of the diffraction orders of a periodic structure.

TL;DR: It is found that the expected dependencies hold as long as both realistic losses and the variation of mode shape with slowdown factor are taken into account, and structures that can achieve the same conversion efficiency as already observed in nanowires for the same input power, yet for a device length that is 50 times shorter are predicted.
