Optical waveguide modes
WebWaveguide modes For a waveguide of two-dimensional transverse optical confinement, there are two degrees of freedom in the transverse xy plane, and the mode index υ … A strip waveguide is basically a strip of the layer confined between cladding layers. The simplest case is a rectangular waveguide, which is formed when the guiding layer of the slab waveguide is restricted in both transverse directions rather than just one. Rectangular waveguides are used in integrated optical circuits and in laser diodes. They are commonly used as the basis of such optical components as Mach–Zehnder interferometers and wavelength division multiplexers. The
