摘要: A light emitting semiconductor device wherein a p-n junction is defined by a ditch and wherein the ditch either extends to a low resistance layer or is away from the low resistance layer at most 1/2 of the width of the ditch is disclosed. It has the merit that the near field pattern is much more uniform than in a prior-art device.
