Development buried ridge stripe isolator configuration

In the BRS technology we developed an alternative isolator configuration, based on lateral current injection in the active core. This configuration has the advantage that the source of the non-reciprocal effect - the MO metal - no longer serves as the electrical contact, hence no absorbing ternary contact layer must be present between the cladding and the MO metal. This allows reducing optical losses in the device.

We have demonstrated experimental operation of the lateral injection leading to similar gain as direct injection device operation.
