英文摘要 | PURPOSE:To obtain a DFB laser element which can operate at a high output by growing a quaternary mixed crystal of GaInAsP by a liquid epitaxial growing method on a bent active layer of a semiconductor laser element having a double hetero structure, and thinly forming an optical guide layer having a flat surface. CONSTITUTION:When a semiconductor laser element of a double hetero structure having current constriction layers 22, 23 at both sides of a V-shaped groove 34, and a clad layer 25, an active layer 27, an optical guide layer 28 and a clad layer 29 formed in on the groove 24 is formed, a quaternary mixed crystal of GaInAsP is grown by a liquid epitaxial growing method on the bent layer 27, and the layer 28 having a flat surface is thinned as much as possible, thereby forming a wavy grating 28a on the flat surface. Thus, leakage currents to the layers 22, 23 are small to operate at a high output, and a flat grown surface can be rapidly obtained even on the bent surface, thereby forming a stable distributed feedback DFB type laser element. |
