1. A light emitting device having a stack of layers including semiconductor layers comprising an active region, said device comprising:
a transparent optical element bonded to a surface of the stack by a bonding layer, wherein the transparent optical element does not extend over sides of the stack of layers, and wherein the bonding layer is selected from the group consisting of glass having an optical index greater than 1.8, Schott glass SF59, Schott glass LaSF 3, and Schott glass LaSF N18. |
