英文摘要 | PURPOSE:To increase the implantation efficiency of the electron and the hole into the quantum well region to be a light emitting layer by a method wherein, in an n type clad layer, the ratio of the hole implanted into an active layer and running out of the active layer is reduced while, in a p type clad layer, the ratio of the electrons implanted into the active layer and running out of the active layer is reduced. CONSTITUTION:An InGaAs active layer 3 is single quantum well structured and then an n type InP clad layer 4 and a p type AlInAs clad layer 5 are multiple quantum well structured while the n=1 quantum level of the electrons and the n=1 quantum level of the hole of the layer 4 and the layer 5 are made larger than that of the active layer 3. Furthermore, potential barrier to the hole of the n type clad layer 4 is made larger than that to the hole of the p type clad layer 5 likewise the potential barrier to the electrons of the p type clad layer 5 is made larger than that to the electrons of the n type clad layer 4. Through these procedures, the implantation efficiency of the electrons and hole into the active layer 3 can be increased thereby decreasing the oscillation threshold value current density simultaneously improving the modulation characteristics as well as the temperature characteristics during the laser oscillation time. |
