FFT Beam Propagation Method

Implementation of the FFT BPM in different optical waveguides and free space

Description

The zip file includes the next programs:

BPM_free_space.m - Propagation of a gaussian pulse in free space

BPM_triangle.m - Propagation of a gaussian pulse in a triangle index profile waveguide

BPM_2step.m - Demonstration of the evanescent waves phenomenon in parallel rectangular waveguides

BPM_Y_Branch.m - FFT-BPM in a Y-branch coupler

BPM_mach_zender.m - FFT-BPM simulation of a mach-zender optical switch

Amazing programs, conglatulations is a great contribution, I can not explaind all the possible aplications

[Eduardo Jiménez]

buen trabajo

[S.K. Arya]

It works very nicely.The m-file of the program can be modified as per the requirement.

[Jim Lee]

Very good!

exelente justo lo que nececitaba

[Dominic Bosomtwi]

excellent programs..........
can someone expalin to me where the waveguide(core) width and the cladding width are handled in the code for the rectangular waveguide? and what do x0, x1, x2,x3,and x4 stand for?

[Julio Cesar Hernandez De Torres]

good, i goona check
