Jeff Chiles

My research interests are all about integrated photonics, but I actively pursue technologies in a lot of smaller topics under that umbrella. One of my core research philosophies is that you should always start with the right platform. If it doesn’t exist, you should make it yourself! So a lot of my work goes into this challenge. I am helping to develop photonic interconnects for cryogenic systems as part of the neuromorphic computing effort here at NIST Boulder, which involves 3D integration, materials development and passive photonic design problems. On the nonlinear photonics side, I’m working on the design and fabrication of high-performance suspended waveguides for frequency comb generation out to LWIR wavelengths.
