Dependence of extrinsic loss on group velocity in photonic crystal waveguides Open
We examine the effects of disorder on propagation loss as a function of group velocity for W1 photonic crystal (PhC) waveguides. Disorder is deliberately and controllably introduced into the photonic crystal by pseudo-randomly displacing t…

Flatband slow light in photonic crystals featuring spatial pulse compression and terahertz bandwidth Open
Paradoxically, slow light promises to increase the speed of telecommunications in novel photonic structures, such as coupled resonators [1] and photonic crystals [2,3]. Apart from signal delays, the key consequence of slowing light down is…

Coupled photonic crystal heterostructure nanocavities Open
We show the first experimental demonstration of multiple heterostructure photonic crystal cavities being coupled together to form a chain of coupled resonators with up to ten cavities. This system allows us to engineer the group velocity o…

Low loss silicon on insulator photonic crystal waveguides made by 193nm optical lithography Open
We show the successful fabrication and operation of photonic crystal waveguides on SOI, with lower silicon dioxide cladding remaining, using 193 nm DUV lithography. We demonstrate that 193 nm lithography gives more process latitude, allowi…
