Zusammenfassung:A method for preparing a VCSEL can use MBE for: growing a first conduction region over a first mirror region; growing an active region over the first conduction region opposite of the first mirror region, including: (a) growing a quantum well barrier having In1-xGaxP(As); (b) growing an transitional layer having one or more of GaP, GaAsP, or GaAs; (c) growing a quantum well layer having In1-zGazAsyP1-y; (d) growing another transitional layer have one or more of GaP, GaAsP, or GaAs; (e) repeating processes (a) through (d) over a plurality of cycles; and (f) growing a quantum well barrier having In1-xGaxP(As); growing a second conduction region over the active region opposite of the first conduction region, wherein: x ranges from 0.77 to 0.50; y ranges from 0.7 to 1; and z ranges from 0.7 to 0.99.
