solution of the inverse scattering problem in 2-D

complex, non-linear combination of gratings

binary grating with λ/4 feature size

computer generated hologram (GDS II file)

or planar waveguide device (PLC)

combines design flexibility of digital holography with manufacturability of planar structures

applicable to most planar waveguide structures

transforms any input intensity, phase, wavelength and polarization into almost arbitrary desirable output

wavelength scalable

resilient to process variations

adaptable to customer's technology

fast design cycles through direct writing

low cost through replication
