| 英文摘要 | PURPOSE:To confine both currents and beams, and to not only reduce the DC threshold but also enable the control of a transverse mode and the simplification of a longitudinal mode jointly by combining current constriction by conventional striped structure and current constriction by mesa structure. CONSTITUTION:With a square mesa section with an active region, both currents and beams are confined by both P-N striped buried layers 60, 70 in the direction of a line A-A' and an insulating material 100 formed by passivating a recessed notched section shaped through chemical etching in the direction of a line B-B'. Consequently, both the control of a transverse mode controlling the form of extension in the lateral direction along a substrate surface of oscillation currents and oscillation output beams and the control and simplification of a longitudinal mode controlling the form of extension in the direction vertical to the substrate surface can sufficiently be attained collectively without generating problems, such as the limit of the reduction of a current threshold, the difficulty of a change into high reflectivity of a mirror layer, the deterioration of thermal radiation properties, the lowering of the strength of mesa structure or the like as seen in conventional devices. |
