2 mm by 2 mm integrated photonic chip

A 2 mm by 2 mm integrated photonic chip 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 applications.
