Modeig98 On-Line Reference

Release 1.1 is HERE!

Congratulations on your choice of optical waveguide modeling programs. Originally written by Robert B. Smith in 1977. MODEIG is used to calculate complex propagating modes in arbitrary, plane-layered, complex dielectric structures and devices, such as optical waveguides and multiple quantum well lasers.

The MODEIG98 update encompasses converting the program code to the FORTRAN 90 programming language thereby enabling cross platform compatibility, as well as the addition of subroutines to calculate the index of refraction for a variety of materials systems.
