英文摘要 | PURPOSE:To make a semiconductor light emitting device of this design large in change of oscillation frequency to the change of a phase control current and to prevent it from varying much in properties of oscillation light. CONSTITUTION:Phase adjusting regions 16a-16c different from each other in thickness and width are provided to two or more parts of an active layer 8 and/or an optical guide layer 6, and two or more phase adjusting electrodes 24a-24c are provided to a first clad layer 12 in contact with the active layer 8 corresponding to the phase adjusting regions 16a-16c. Therefore, even if an injection current is decreased in volume per phase adjusting electrode, oscillation frequencies can be made large in change as a whole. As injection current can be made small in quantity per phase adjusting electrode, oscillation light can be made small in variation. By this setup, the change of oscillation frequencies can be made large to the change of a phase control current, and a modulated wave excellent in quality can be obtained without varying oscillation light in properties. |
