Fabrication and transfer print based integration of free-standing GaN membrane micro-lenses onto semiconductor chips
Nils Kolja Wessling, Saptarsi Ghosh, Benoit Guilhabert +5
We demonstrate the back-end integration of broadband, high-NA GaN micro-lenses by micro-assembly onto non-native semiconductor substrates. We developed a highly parallel micro-fabr…
