Abstract :
The theory of Hermite-Gaussian beam waveguide modes is briefly reviewed, leading to expressions for the paraxial vector electric and magnetic fields for wave modes of arbitrary order. The variation of field amplitude in the transverse xy-plane is depicted by three-dimensional graphs, and constant-amplitude contour plots are derived. Also, the electric and magnetic field lines in longitudinal xz- and yz-planes are plotted for transverse modal orders ranging from (0,0) to (2,2)
