At the heart of IWGs are waveguides meticulously inscribed by femtosecond laser processes. This produces garnet slabs where Faraday rotation characteristics are preserved and that can guide light like any other waveguide.
The compact lens-less design and the flexibility of mounting options offered by IWG isolators means they can be easily integrated into existing systems, avoiding costly modifications.

In this paper we demonstrate an innovative approach that allows to make submillimeter-size magnetless passive optical isolators having the potential of being easily integrated in PICs.
