    • A vertical cavity laser array device (100) including a substrate (110), top (140) and bottom (120) dielectric stacks, and an active region (130) for producing laser light. The active region includes one or more periodic gain region(s) (160) and spacer layers (170) disposed on either side of the periodic gain region(s) (160) and arranged so that the periodic gain region(s) is aligned with the antinodes of the device's standing wave electromagnetic field. A structure is provided for modulating the properties of the periodic gain region(s) at spaced locations (150) so as to provide an array of spaced laser pixels (200) which have higher net gain than the interpixel regions (210); and the spaced laser pixels (200) having the same or different sizes and the spacings between pixels having the same or different lengths to cause the output of the vertical cavity laser array device to produce single or multimode laser output.
    • 包括衬底(110),顶部(140)和底部(120)电介质叠层的垂直腔激光器阵列器件(100)和用于产生激光的有源区域(130)。 有源区域包括设置在周期性增益区域(160)的任一侧上的一个或多个周期性增益区域(160)和间隔层(170),并被布置为使得周期性增益区域对齐 与设备的驻波电磁场的波腹。 提供了一种用于调制间隔位置(150)处的周期性增益区域的特性的结构,以便提供具有比像素间区域(210)更高的净增益的间隔开的激光像素阵列(200); 并且具有相同或不同尺寸的间隔激光像素(200)和具有相同或不同长度的像素之间的间距导致垂直腔激光器阵列器件的输出产生单模或多模激光输出。
