Multi-layer dispersion-engineered waveguides and resonators

   
   

A multi-layer laterally-confined dispersion-engineered optical waveguide may include one multi-layer reflector stack for guiding an optical mode along a surface thereof, or may include two multi-layer reflector stacks with a core therebetween for guiding an optical mode along the core. Dispersive properties of such multi-layer waveguides enable modal-index-matching between low-index optical fibers and/or waveguides and high-index integrated optical components and efficient transfer of optical signal power therebetween. Integrated optical devices incorporating such multi-layer waveguides may therefore exhibit low (<3 dB) insertion losses. Incorporation of an active layer (electro-optic, electro-absorptive, non-linear-optical) into such waveguides enables active control of optical loss and/or modal index with relatively low-voltage/low-intensity control signals. Integrated optical devices incorporating such waveguides may therefore exhibit relatively low drive signal requirements.

Um waveguide ótico dispersão-projetado lateral-confinado multi-layer pode incluir uma pilha multi-layer do refletor para guiar uma modalidade ótica ao longo de uma superfície disso, ou pode incluir duas pilhas multi-layer do refletor com um núcleo therebetween guiando uma modalidade ótica ao longo do núcleo. As propriedades dispersive de tais waveguides multi-layer permitem modal-índice-combinar entre fibras óticas do baixo-índice e/ou os waveguides e os componentes óticos integrados elevado-índice e transferência eficiente do poder do sinal ótico therebetween. Os dispositivos óticos integrados que incorporam tais waveguides multi-layer podem conseqüentemente exibir o ponto baixo (
