MODEIG calculates the complex eigenmodes of electromagnetic waves
propagating in plane-layered structures composed of homogeneous,
isotropic materials having arbitrary complex dielectric properties.  

History of MODEIG
Dr. Jay Harris, a professor at the University of Washington from the
mid 60s to the late 70s, obtained support from Dr. E. Schutzman,
a program manager at the National Science Foundation under contract
ENG 76-009337 to develop a computer program to calculate the complex
eigenmodes of electromagnetic waves propagating in plane-layered
structures composed of homogeneous, isotropic materials having
arbitrary complex dielectric properties.  The result of this support
was MODEIG, which solves completely general planar structures
consisting of any number of guiding and non-guiding layers, with loss
or gain in each layer.

Robert B. Smith, a graduate student at the time, took on the task of
writing MODEIG.  He was assisted by Gordon L. Mitchel, who having
recently completed his Ph.D. with Professor Harris remained at the
UW as a post-doctoral fellow.  In 1977, Professor Harris took a leave
of absence which he spent at the National Science Foundation.  As a
result of Professor Harris's leave, Professor Akira Ishimaru became a
co-advisor to Robert Smith.  In addition, Professor Harris's leave
opened up a visiting assistant professor position at the UW which, as
a native Washingtonian and UW undergrad (from 1966-70) with a
relatively fresh Ph.D. from Caltech, I was happy to fill. 

When I met Robert Smith at the UW in 1977 and heard him describe the
capabilities of MODEIG, I was impressed, having written much less
ambitious programs for simple dielectric waveguides (three layer
planar guides, circular fibers, and diffused waveguides).  When I
left the UW in 1979 to work on semiconductor lasers at the Aerospace
Corporation, I took with me a copy of Robert Smith's thesis (available
from University Microfilms) which contains the original MODEIG source
code.  With the help of the many people listed below, I have been
using and modifying MODEIG ever since.

  THE TRANSFORMATION OF THE ORIGINAL VERSION OF MODEIG TO MAKE IT
  MORE USEFUL FOR SEMICONDUCTOR LASER MODELLING WAS MADE UNDER THE 
  GUIDANCE OF GARY EVANS FROM 1979-1998 AT THE AEROSPACE CORPORATION,            
  TRW, RCA LABORATORIES, AND SMU.  THE PHYSICAL CONCEPTS IN THESE 
  REVISIONS WERE DEVELOPED BY GARY EVANS AND JEROME BUTLER.
