          Appeal No. 1998-2938                                                        
          Application 08/510,752                                                      

          lines 17-19):  "[The Zhou paper] describes a strained quantum               
          well with a graded composition providing a value of strain                  
          that is graded in magnitude from one side of the well to the                
          other."  Of course, there still remains the question of                     
          whether the quantum well layer strain profile has the property              
          of "substantially matching E1-HH1 and E1-LH1 Stark shifts for               
          at least one polarity of applied electric field from 0 up to                
          100 kV/cm and zero field E1-LH1 and E1-HH1 transitions that                 
          are substantially degenerate."
