Abstract
본 발명은 이저 다이오드에 관한 것으로서, 특히 전류 제한 특성이 향상되고 본딩 압력에 효과적으로 대응할 수 있도록 구조 개선된 레이저 다이오드에 관한 것이다. 본 발명 레이저 다이오드는 n-금속 전극층이 형성된 기판과, 기판에 상면에 순차형성되는 n+ 버퍼층, n- 크래딩 레이어, 레이저 발진층과, 그 중앙에 돌출된 리지가 마련된 p-크래딩 레이어와, 상기 리지의 상면에 형성되는 p+ 캡 레이어와, 상기 p+ 캡 레이어의 위에 형성되는 p+ 콘택트 레이어와, 상기 캡 레이어를 제외한 부위를 포함하여 상기 리지부분의 보호를 위한 도핑되지 않은 GaAs층과, 상기 단층의 최상위에 형성되는 p-금속 전극을 갖추며, 상기 p-크래딩 레이어의 리지와 리지 상부에 마련된 캡 레이어 및 콘택트 레이어에 p++ 도핑이 되어 있다. 이로써, 리지 부분이 물리적 강도가 강화되기 때문에 본딩 작업시 특성 열화등과 같은 문제가 발생되지 않으며, 그리고 리지 부분이 p++ 도핑이 되어 있으므로 우수한 전류 제한 효과를 거둘 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a laser diode, and more particularly, to a laser diode whose structure is improved so that current limiting characteristics can be improved and effectively respond to bonding pressure. The laser diode of the present invention comprises: a substrate on which an n-metal electrode layer is formed, an n + buffer layer, an n-cladding layer, a laser oscillation layer, and a p-cladding layer provided with a ridge protruding at the center thereof; A p + cap layer formed on the upper surface of the ridge, a p + contact layer formed on the p + cap layer, an undoped GaAs layer for protecting the ridge portion, including portions other than the cap layer, and the monolayer It has a p-metal electrode formed at the top of the p-doping, and the cap layer and the contact layer provided on the ridge and the ridge of the p- cladding layer is p ++ doped. As a result, problems such as deterioration of characteristics during the bonding operation are not generated because the ridge portion has enhanced physical strength, and since the ridge portion is p ++ doped, excellent current limiting effect can be obtained.
