    摘要: A photonic quantum ring (PQR) laser diode with a plurality of laterally extending layers, one on top of another in an axial stack, comprises an active region sandwiched between an n type multi-layer distributed Bragg reflector (DBR) stack and a p type multi-layer DBR stack, wherein, along the circumference of said active region, 3 dimensional radiations are emitted with various wavelengths over a predetermined tuning range, as a function of slanted view angle with respect to the stack axis. The PQR laser shows an ultra-low threshold current of &mgr;A range, T½ dependence of the spectral peak shift and a square law behavior of threshold currents.
