Paper Abstract

(Invited) Subwavelength grating metamaterial waveguide devices are becoming established as key building blocks for silicon photonic integrated circuits. The novel optical properties found in these structures and ability to control their optical responses with unprecedented accuracy are opening new prospects for controlling and manipulating light in planar waveguides. Subwavelength grating metamaterial waveguides have attracted a strong research interest in academia and industry and many advanced devices with unprecedented performance have been demonstrated. The subwavelength engineered silicon waveguides have been adopted by industry for fiber-chip coupling and subwavelength engineered structures in general are likely to become key building blocks for the next generation of integrated photonic circuits. In this invited talk we will present an overview of our recent advances in this exciting field, including silicon-based subwavelength structures for highly efficient fiber-chip couplers, ultra-broadband waveguide devices, Bragg filters with high spectral sensitivity and nanophotonic waveguides with engineered anisotropy.
