| 英文摘要 | A light emitting chip having a buried hetero-structure has a laser region consisting of a buffer layer (2), an active layer (3) and a cladding layer (4) formed on a body (1). Contact layers (8, 9) form a neck (7) in the laser region (2, 3, 4). At least a part of the active layer (3) lies between the neck (7) and the body (1), and in contact with the plane (B) of the contact layers (8, 9) on which no atoms of light impurity elements are found; a better contact is made and leakage is reduced. An improved current optical output characteristic is achieved and the threshold current is reduced. |
