In a combination of physics and materials science, Princeton researchers found that a type of foam can selectively block light, which is important for next-generation devices that compute with light instead of electricity.

There is more to foam than meets the eye. Literally. A study by Princeton scientists has shown that a type of foam long studied by researchers is able to block particular wavelengths of light, a coveted property for next-generation information technology that uses light instead of electricity.
