    • A semiconductor laser particularly useful for frequency multiplexing in optical telecommunications having a distributed resonator supplying from a single etched grating, two or more radiations of different wavelengths. The laser comprises a junction formed by an n-type substrate, a p-type radiation-confinement region, and a surface region, a grating being etched at the interface between the confinement region and the surface region. Useful elementary bands of the junction for the attainment of the laser effect are fixed by proton implantation in the surface region of the junction. The elementary band-type regions are convergent and form, with the perpendicular to the grooves of the grating, angles that are determined so that the spacing along the various bands has a specified value linked directly to the wavelength of the corresponding emitted radiation.
    • 一种特别适用于光通信中的频率复用的半导体激光器,其具有从单个蚀刻光栅提供的分布式谐振器,两个或更多个不同波长的辐射。 激光器包括由n型衬底,p型辐射限制区域和表面区域形成的结,光栅在限制区域和表面区域之间的界面处被蚀刻。 用于获得激光效应的连接点的有用元件带通过质子注入固定在结的表面区域中。 基本带状区域会聚并形成与光栅的凹槽垂直的角度,其角度被确定为使得沿着各个波段的间隔具有直接与对应的发射辐射的波长相关的特定值。
