The Beta version is not claimed to be bug free. The purpose of this Beta version, is to get feedback from the users as to problems with the interface, undiscovered bugs etc. This process really gives the users a say in how the finished version will appear.

The users of this version are STRONGLY advised to double check the calculations with an older verion of MODEIG.

Listed below, is a revision history for the current BETA version. (please scroll down)

• BETA 1.2
  • Improvements over Beta version 1.1 (and Release 1.1 - not including additional material system.) Include:
    • Ability to support up to 100 layers.

• RELEASE 1.1
  • Improvements over Beta version 1.1 Include:
    • The addition of the following material systems;
      • InGaAsP (lattice matched to InP)

• BETA 1.1
  • Improvements over Beta version 1.0 Include:
  • The addition of the following material systems;
    • Al(x)Ga(1-x)As
    • In(1-X)Ga(X)As(Y)P(1-Y)
    • Al(X)Ga(Y)In(1-X-Y)As
    • Al(X)Ga(1-X)P(Y)Sb(1-Y)
    • Al(X)Ga(1-X)As(Y)Sb(1-Y)
    • Al(X)In(1-X)As(Y)Sb(1-Y)
    • Ga(X)In(1-X)P(Y)Sb(1-Y)
    • AlAs(X)Sb(1-X)
    • (Al(x)Ga(1-x))0.5In(0.5)P
    • In(1-x)Ga(x)As [matched to InP ]
    • In(1-x)Ga(x)As [matched to GaAs]
    • Ga(x)In(1-x)P [matched to GaAs]
  • Addition of the overlap routine which is used to compute the overlap integral of multiple near field files
  • An option to include/exclude the '*' for cricket graph
  • Bugs dealing with the presence of output files were eliminated
  • All error messages will now be returned (previous beta version would not complain if an incorrect input card was being used)
  • input files are no longer required to be in all uppercase i.e. they are no longer case sensitive
  • INITGS (initial guess) now works.

• BETA 1.0
