Analysis of a Multilayer Slab Waveguide for Edge-Coupled THz Photomixer Applications

A multilayer dielectric slab waveguide for the edge-coupled terahertz photomixer source applications is studied. The top layer of the dielectric waveguide structure is made of an ultra-fast photo-absorbing material, wherein the power of the guided modes are being absorbed and converted into a terahertz signal. The optical field and power distributions inside the waveguide structure are presented.
