Waveguide sub‐wavelength structures: a review of principles and applications. Issue 1 (30th September 2014) - Halir, Robert
Abstract With the recent development of silicon photonics and high resolution lithography, periodic structures with a sub‐wavelength pitch have found widespread application. This review provides an introduction to the physics of sub‐wavelength structures and an extensive overview of their applications in waveguide devices, including: high efficiency fiber‐chip couplers, wavelength multiplexers, athermal waveguide and ultra‐broadband waveguide couplers.
