We report a novel grating-assisted coupler that incorporates a photonic-band-gap structure. It is shown that by virtue of the resonant cavity formed by the structure and the grating the relative amounts of the output scattered and the transmitted guided-wave powers can be significantly modified. The potential applications for optical switches and wavelength(More)
SUMMARY In this review paper we showcase recent activities on silicon photonics science and technology research in Hong Kong regarding two important topical areas — microresonator devices and optical nonlin-earities. Our work on silicon microresonator filters, switches and modula-tors have shown promise for the nascent development of on-chip optoelec-tronic(More)
