Researchers show optical properties of metals can be tuned opening new route to programmable nanophotonic devices
Researchers tune metal's optical properties through strain.

In a significant development, researchers from Bengaluru have shown for the first time that how a metal interacts with light can be actively tuned by applying mechanical strain.
This finding challenges a long-held assumption in physics that the optical properties of metals are unchangeable. It opens new pathways for building reconfigurable optical devices compatible with standard semiconductor manufacturing.
Directly tuning optical properties of materials could revolutionize device fabrication.
