I have NO idea if this has relevance to Lightwave, but I thought I'd share it for our techie-types to take a look at. Feedback is welcomed. I follow NISt in LinkedIn for nuggets related to the NIST Collaboration that was announced over 18 months ago...

"NIST researchers have demonstrated a new way to transmit light signals through a chip. Space on a tiny chip is precious real estate, and the researchers’ new design requires less space and fewer optical components.Waveguides are devices that can direct light from one point to another with little signal loss. Optical circuits on modern chips have multiple layers for guiding light and encoding information on them. However, light from one layer can leak into another layer by jumping over the narrow gap between them.NIST researchers designed a device, called a bound in continuum (BIC) waveguide, that prohibits light from jumping the gap. Moreover, the waveguide can simultaneously direct two separate light waves in the two layers. Conventional optical circuits contain beam splitters that separate the light into two or more waves. In the new design light goes directly to the BIC waveguide, splitting it into separate waves. After manipulating one of the waves with an electrical signal to encode data, the light waves later recombine to form the desired optical signal. The new chip-scale device is made up of a solid slab of lithium niobate material that sits on top of a ridge of silicon nitride. This novel waveguide approach opens up new creative space for designing different types of optical circuits.
