Thus, for the electron, the envelope wave function reads  ( r )  e im e ( 2 ) 1 /2 (2ne ! b)  ( 2 ) 1 / 2 e im e R  (  ) 1 ( z ) m   with Ln ee denoting Laguerre polynomials, ne  0 ,1,2 ,... , me  0 ,  1,  2 ,... , le    e  e , and  re-denoting the set ( ne , me ) for i  1 . The corresponding energy states are obtained as     n e m e   1ez , where  neme and  1ez are the quantized e values of   and  ze , respectively. The quantized energy for the in-plane motion is  ne me  2 n e  m e  1 e .

Light output-injection current curves measured at 20C under continuous-wave operation mode. The inset shows the schematic drawing of the tapered waveguide. Fig. 14 shows the output power against the injection current density for 1mm and 2mm long devices measured at 20ºC under continuous-wave operation conditions. 54mW under an injection current of 3kA/cm2 was achieved in 1mm long device. 22 Fingerprints in the Optical and Transport Properties of Quantum Dots Above 3kA/cm2, the output power decreases due to the thermal effect caused by relatively high series resistance as measured in our devices.

2005; Cheche & Chang, 2005) in this section a non-adiabatic treatment of optical absorption in QDs is presented. The theoretical tool we develop: i) confirms existence of resonances accompanying the LO satellites in the optical spectra; ii) explains the temperature effect on the optical spectra. 1, bq ( bq ) are the bosonic creation (annihilation) operators of the phonons of mode q , M qff '  f M q f ' is the coupling matrix element, q is the frequency of the phonon mode with wave vector q , and E f ( f ) are the EHP eigenvalues (eigenstates) of the exciton system.
