Abstract
An environmentally protected PIC, including an InP-based substrate having a first surface that is at least partially provided with an InP-based optical waveguide, and a dielectric protective layer arranged to cover at least the first surface of the InP-based substrate and the InP-based optical waveguide. The dielectric protective layer is configured to protect said PIC from environmental contaminants, to enable confinement of optical radiation in the dielectric protective layer in at least one direction that is transverse to a direction of propagation of the optical radiation, and to allow exchange of the optical radiation between the InP-based optical waveguide and the dielectric protective layer. An opto-electronic system including PIC.
