WebbThe aim is to connect each horizontal lines of each space to assume transmission of electromagnetic waves. Thus in geometric approximation, each ray of light in the first waveguide is guided into the second one by green lines representing the taper. WebbElectromagnetic (e.m.) simulation of the cavity-waveguide system. ( a) Transmission towards ports 2 or 3 (dotted lines), reflection towards port 1 (full lines) and radiated fraction of the optical power (dashed lines) for = 1615 nm in the geometry of Figure 1 a. Transmission at port 4 is almost zero. ( b) Energy density inside the cavity.
WebbUsing a generalized reciprocity theorem for waveguide junctions, a previous quasi-optic solution of this problem is extended to account for reflected waves. The results have … WebbThere are several fundamental methods available for exciting SPR, including prism coupling, waveguide coupling, and grating coupling methods as shown in Figure 1. The most conventional approach is the Kretschmann method, which employs a prism coupler with a thin metal film, as shown in Figure 1 (a). Figure 1.
