Abstract
A light source includes an array of micro-light emitting diodes (micro-LEDs), an array of micro-lenses, and a bonding layer bonding the array of micro-lenses to the array of micro-LEDs. Each micro-LED of the array of micro-LEDs includes a first mesa structure formed in a plurality of semiconductor layers. The array of micro-lenses is bonded to a first semiconductor layer of the plurality of semiconductor layers by the bonding layer. The first semiconductor layer includes an array of second mesa structures formed therein. The first mesa structure and the second mesa structure are on opposite sides of the plurality of semiconductor layers. Each second mesa structure of the array of second mesa structures is aligned with a respective micro-lens of the array of micro-lenses and the first mesa structure of a respective micro-LED of the array of micro-LEDs.
