Abstract :
Summary form only given. In this paper, we present a novel structure of 1.3 μm strained-layer multiple quantum well (MQW) complex-coupled DFB laser with automatically buried absorptive grating. These lasers can be fabricated by a very simple process and show high single-mode performance. An InAsP absorptive grating is selectively formed on the concave region of the corrugated InP substrate.
