WGmode

2D simulation functions for slab and ridge waveguide mode study

Folders structure

2Dmode_profile

Includes two main functions to simulate:

• Slab waveguide
• Ridge waveguide: "effective index" approximation

Input parameters

• n1 = 2.038; % core Si3N4 3.48 2.038 (glass 1.5)
• n0 = 1.5; % cladding Sample Media 1.33
• ns = 1.5; % substrate SiO2 1.4
• lambda = 0.647; % um 1.5
• NAObj = 0.55;
• Fobj = 4; % [mm]
• beamD = 8; % [mm] % beack aperture obj: beam size at the back obj

dispertionCurve

Includes two main functions:

• plotDispCurveTE
• plotDispCurveTM

penetrationDepth

Include two main functions:

• penetraitonDepthCore: to show how the penetration depth/effective index change with wg core size
• penetrationDepth: to show how the penetration depth/effective index change with other set of parameters
