TL;DR: In this paper, the authors present an extensive analysis, both from a practical and a theoretical perspective, of current biosensors, and analyze how subwavelength structures can be exploited to enhance their sensitivity.

TL;DR: A new type of surface-emitting silicon waveguide with a dramatically increased antenna length of L=3.65mm is reported on, achieved by using a subwavelength metamaterial waveguide core evanescently coupled with radiative segments laterally separated from the core.

TL;DR: A distributed Bragg deflector is presented that enables well controlled coupling from a waveguide mode to such a 2D on-chip beam and it is demonstrated via a rigorous simulation that two such couplers in a back-to-back configuration efficiently couple light.

TL;DR: In this article, a 2-millimeter-long, single-etched subwavelength-engineered optical antenna with a lateral periodic array of radiative elements is presented.
