Backside thinning techniques critically influence GaN laser performance. Compared to lapping, grinding reduces subsurface damage depth fivefold and lowers wafer bow, while mechanical polishing eliminates subsurface damage entirely. These improvements directly translate to smoother cleaved facets and a nearly 40% reduction in laser threshold current ...
