In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade. The ...
GaN-based vertical-cavity surface-emitting lasers (VCSELs) are promising for displays, sensing and optical communication, but improving efficiency remains challenging. Researchers have now shown that ...
Vertical-cavity surface-emitting lasers (VCSELs) are semiconductor devices that emit light perpendicular to the wafer surface, combining low threshold currents, compact size and high modulation ...
