Abstract
A flower-type photonic quantum ring (PQR) laser for enhanced output power of about five times that expected from circular PQR lasers of the same size has been designed and fabricated. The multi-petal flower design, combining concave and convex whispering cave modes, increases the overall quantum wire length of the emitting PQR within the same device area.
