Tiny Photonic Chip Provides a Big Boost in Precision Optics

A 2 mm by 2 mm integrated photonic chip developed by Jaime Cardenas, assistant professor of optics, and PhD student Meiting Song (lead author) will make interferometers—and therefore precision optics—even more powerful. Potential applications include more sensitive devices for measuring tiny flaws on mirrors, or dispersion of pollutants in the atmosphere, and ultimately, quantum...

Cutting-edge Technology for Building Ultralow-Loss Incorporated Photonic Circuits

Encoding data into light and transferring it using fiber optics is at the core of optical communications. With an exceptionally minimal loss of 0.2 dB/km, fiber optics made from silica have laid the foundations of today's international telecommunication networks and our data society.Such ultralow optical loss is just as crucial for incorporated photonics, which...
