Abstract
The present invention discloses a plurality of interdigitated pixels arranged in an array, having a very low series-resistance with improved current spreading and improved heat-sinking. Each pixel is a square with sides of dimension l. The series resistance is minimized by increasing the perimeter of an active region for the pixels. The series resistance is also minimized by shrinking the space between a mesa and n-contact for each pixel.
