Abstract
An optoelectronic device includes a semiconductor substrate and a monolithic array of light-emitting elements, including first and second sets of the light-emitting elements arranged on the substrate in respective first and second two-dimensional patterns, which are interleaved on the substrate. First and second conductors are respectively connected to separately drive the first and second sets of the light-emitting elements so that the device selectably emits light in either or both of the first and second patterns.
