Conformal metasurface coating eliminates crosstalk and shrinks waveguides

Conformal metasurface coating eliminates crosstalk and shrinks waveguides 08/31/2017 05:51 PM EDT The properties of materials can behave in funny ways. Tweak one aspect to make a device smaller or less leaky, for example, and something else might change in an undesirable way, so that engineers play a game of balancing one characteristic against another. Now, a team of Penn State electrical engineers have a way to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a near zero thickness and weight.
