New Light from Semiconductor Defects

OPTICS & PHOTONICS “V-pits” in structure of InGaN LEDs can serve as sources of long-wavelength light, potentially enabling CMOS-compatible, full-visible-spectrum LEDs without added phosphors.

Sensors, Cities and Climate Change

OPTICS & PHOTONICS Summit in Glasgow, held in parallel with COP26, focused on how real-time tracking of urban emissions—via photonically enabled sensors—could constitute a vital tool in climate action.
