Original Abstract Submitted
An integrated emitter device incudes a silicon die, including an array of control circuits, and a plurality of integrated emitter modules disposed on the silicon die. Each integrated emitter module includes a single epitaxial stack comprising multiple layers of III-V semiconductor compounds, which define a vertical emitter including an optically active layer and upper and lower distributed Bragg reflectors (DBRs) on opposing sides of the optically active layer, and a transistor in series with the vertical emitter and including a terminal in contact with a respective one of the control circuits, so as to actuate the vertical emitter in response to a control signal applied to the terminal by the respective one of the control circuits.
