Nanophotonic UV

Over the past decade, we have developed a wide range of “building blocks” to advance nitride-integrated photonics devices.

Our UV microphotoluminescence platform has been enhanced with new spectroscopy and imaging techniques, allowing us to demonstrate the first deep-UV microdisk laser, emitting at 275 nm under optical pumping, as well as a complete series of microdisk lasers spanning the blue to UV spectrum.

In 2018, these microdisk lasers were integrated with a waveguide and light extraction gratings, marking a first in the field of integrated photonics with a nitride microlaser.
