| 英文摘要 | PURPOSE:To achieve a uniform carrier injection operation and to obtain a quantum well laser whose modulation band is wide and whose oscillation spectrum width is narrow by a method wherein the lattice constant of a semiconductor forming a barrier layer is made smaller than the lattice constant of a substrate. CONSTITUTION:The manufacturing method is as follows: an n-InP buffer layer 14 is grown in 0.1mum on an n-InP substrate 15 by an MOVPE method; an In0.6 Ga0.4As0.6P0.4 barrier 12 composed of a composition whose lattice constant is by 0.5% smaller than that of InP is grown in 80 R; and an In0.53Ga0.47As well 13 is grown in 70Angstrom on it. The growth operation of the well and the barrier is repeated 10 times; and a 10-layer mutilple quantum well structure is manufactured. In addition, a p-InP clad layer 11 is grown in about 1mum on it. A multiple quantum well semiconductor wafer, having a strain barrier, which is manufactured in this manner is buried in a DC-PBH structure. Lastly, a p-side electrode and an n-side electrode are vapor-deposited. |
