ABSTRACT:
A high efficiency, high density light-emitting diode array which provides improved light output efficiency and suppression of crosstalk between adjacent light-emitting elements without loss of reliability or reproducibility is disclosed. The array includes isolated light-emitting elements on a substrate. Each light-emitting element has a light-emitting layer between a pair of cladding layers with heterojunctions being formed between the light-emitting layer and the cladding layers. Each light-emitting element has a light-emitting surface and the light-emitting layer of each light-emitting element is of an area no greater than the area of the light-emitting surface.
