Sp. Pogossian et al., Study of leaky waves: application to hollow waveguides, to ARROW waveguides and to the SiGe LEDs, J MOD OPT, 47(5), 2000, pp. 917-930
In this paper a new approach is proposed for the determination of resonance
characteristics of leaky guiding structures. We show that in the conventio
nal transfer matrix approach some modifications are needed for the descript
ion of leaky structures. Our approach is based on resonance considerations
and does not make recourse to complex propagation constants. It is applied
to hollow and ARROW waveguides. We have used this approach for the optimiza
tion of the vertical LEDs based on SiGe.
