We report on the monolithic integration of RGB InGaN dot-in-a-wire LEDs on a single chip. The correlated color temperature can be continuously varied in the range of 1900K to 6800K, while maintaining excellent color rendering index capability (CRI>90). Moreover, submicron scale RGB pixels were demonstrated.
A monolithic integrated photonic platform is essentially required for a broad range of applications, including optical interconnect, quantum information processing, lighting, display, and sensing. To date, however, a ubiquitous platform for photonic integration has remained elusive. While Si photonics has been extensively studied, it has several serious shortcomings [1], including optical absorption...
