INTEGRATED OPTICAL STRUCTURE COMPRISING AN OPTICAL ISOLATOR

摘要

An integrated optical structure includes at least one optical isolator, having a magneto-optical layer, associated with at least one SOA optical amplifier having a waveguide having an n-doped semiconductor layer, a p-doped semiconductor layer, and an active area disposed between the n-doped semiconductor layer and the p-doped semiconductor layer. The optical isolator is disposed between an SOI base and the SOA optical amplifier's waveguide. The optical isolator's magneto-optical layer is disposed between a lower insulating layer and an upper insulating layer. The optical isolator's magneto-optical layer may be a layer of ferromagnetic metallic material, such as a Fe—Co metallic alloy, or a magnetic oxide layer. An optical device includes at least one integrated optical structure.
