Abstract
Organic-inorganic hybrid material realized by sol-gel process is a new promising technology for the fabrication of integrated optical circuits. Effective devices are already achieved. Two approaches are studied here to improve the density of integration: crossed and stacked waveguides. Both processes are compatible with our organic-inorganic material. One level devices with crossing waveguides as well as multilevel devices have been studied and made: neither additional insertion loss nor crosstalk have been measured. Theoretical studies show the possibility to fabricate vertical coupler in a multilevel structure by adjusting the buffer layer thickness between guiding layers.
