| 摘要 |
A method of fabricating a semiconductor laser diode in the (Al,Ga,In)N materials system comprises: growing, in sequence, a first cladding region (4), a first optical guiding region (5), an active region (6), a second optical guiding region (7) and a second cladding region (8). Each of the first cladding region (4), the first optical guiding region (5), the active region (6), the second optical guiding region (7) and the second cladding region (8) is deposited by molecular beam epitaxy. The nitrogen content of the semiconductor layers is improved by locating an ammonia source in close proximity to the substrate (figure 5). |
