abstract = "We propose here a new light source with a light beam steering mechanism. The direction of the light beam emitted from an array of the light emitting diodes (LEDs) can be changed by a micro-actuator. The proposed device is monolithically composed of the GaN LEDs and Si MEMS structure. Basic researches on the growth of GaN crystals on Si substrate were carried out. Quantum well (QW) structures consisting of InGaN/GaN crystals were formed with a buffer layer between the GaN crystal and Si substrate. Column-like GaN crystals with the QWs were grown Due to the column structure and the buffer layer, the crystals were relaxed enough to obtain strong photoluminescence. From Si substrate with GaN crystal, a micro-stage with comb actuators on which the InGaN/GaN QW film is patterned has also been fabricated.",
