Abstract:
1. A light source comprising: an electrically-conducting substrate; a light emitting structure comprising: a first layer of semiconductor material of a first conductivity type overlying said substrate; an active layer overlying said first layer; and a second layer of semiconductor material of an opposite conductivity type from said first conductivity type overlying said active layer; a barrier that divides said light emitting structure into first and second segments that are electrically isolated from one another; a connection electrode that connects said first layer in said first segment to said second layer in said second segment; and a mirror in electrical contact with said first layer in each of said segments, said connection electrode connecting said mirror in said first segment to said second layer in said second segment, wherein said substrate comprises first and second isolation regions that electrically isolate said minor in said first and second segments from each other, and wherein said electrically-conducting substrate comprises a first conductivity type of silicon and said first and second isolation regions comprise a region of a second conductivity type in said silicon.
