File Information
Description

Calculate the electromagnetic eigenmodes and propagation constants of optical waveguides using the finite difference method. Features:

1. Includes vector, semivector, and scalar versions.

2. Can solve for all components of E and H.

3. Allows for perfectly-matched boundary layers.

4. Can model transverse anisotropic materials.

5. Several examples included

It's an excellent problem for solving waveguides without difficult.
Simple and fast to use with a clean code.

it is very good work it helps me so much

This is great. Do you know how to analyse the optical waveguide using finite element method?

Excellent work

do you know how to analysis optical buried waveguide channel using finite difference method

18 Dec 2007 Satomi Ono

I find it hard to start using it from the very beginning. A bit more explanation about how to use the code would be of great help.

There may be some errors in the formulation of axye axyw ayxn ayxs in "wgmodes.m".

They can't reduce to the formulation presented in "P.Lusse; P.Stuwe; etc., "Analysis of vectorial mode fields in optical waveguides by a new finite difference method," Lightwave Technology, Journal of , vol.12, no.3, pp.487-494, Mar 1994"

I have recently updated the code to correct an algebraic error in the expressions for Axy(E), Axy(W), Ayx(N) and Ayx(S). Many thanks to yuchunlu_china@hotmail.com for pointing out this bug.

Yeah,it's a good frequency domain mode solver in the web. It's excellent for dielectric waveguide structures like SOI ridge waveguide.
But I find that it can not solve waveguide structures including metal material. Hope to find the improvement at this point.

this is good

good work. Can u pl. upload matlab codes for simulation of circular and rectangular waveguides? I am trying to work on the paper:"Analysing electromagnetic structures with curved boundaries on cartesian FDTD meshes" by Yang Hao and Chris J. Railton. Hope I get some help in this regard.

I am trying to run the polymer waveguide example but I keep on receiving error messages as shown below:
generating index mesh...
??? Undefined command/function 'waveguidemeshfull'.

Error in ==> polymer_waveguide at 39
[x,y,xc,yc,nx,ny,epsxx] = waveguidemeshfull([n1,sqrt(e2xx),n3], ...
rror in ==> waveguidemesh at 31
ih = round(h/dy);

generating index mesh...
??? Undefined command/function 'waveguidemesh'.

Error in ==> silicon_channel at 23
[x,y,xc,yc,nx,ny,eps] = ...

can you please help me on what to do?
Thankyou
Gabriel

Well this mode solver is briliant, however I was wondering if it is possible to extract mode area from the mode solver. Means, I calculate modes with wgmodes and after get somehow the modal area? I am looking forward to hearing from you as soon as you have some time to answer.

Fixed bug in auxilliary file: stretchmesh.m

10 Oct 2007

New version includes several significant improvements, including the ability to model anisotropic waveguides. Interface has been simplified.

11 Jan 2008

Corrected an algebraic error in the expressions for the coefficients Axy(E), Axy(W), Axy(N) and Axy(S). Many thanks to yuchunlu_china@hotmail.com for pointing out this bug.

28 Mar 2011

Minor modifications in the examples, and contour plotting subroutine.

22 Apr 2011

Corrected bug in stretchmesh routine for south and west boundaries. Also corrected a bug in wgmodes and svmodes in which dy was incorrected conjugated.

(Thanks to Jiri Petracek for discovering this bug.)
