“…InGaN/GaN-based visible light laser diodes, due to their high brightness and high efficiency [ 1 ], are the subject of many important applications in solid-state lighting [ 2 , 3 ], display applications [ 2 , 4 ], car headlights [ 5 , 6 ], projectors [ 7 , 8 ], atomic clocks [ 9 , 10 ], and laser-based high-density storage systems [ 11 ]. Moreover, these devices are crucial components for emerging visible light communication systems [ 12 , 13 , 14 ]. All applications that utilize visible laser diode technologies are based so far on edge-emitting devices (Edge-Emitting Lasers—EEL).…”
