“…Hence a combination of a series of implantation sessions, at different initial energies, through a respective set of stopping masks can be used to form complex multi-level 3D structures, with submicron features within the depth of a substrate. In addition to the RI reduction induced by the amorphization, the implantation of protons at high fluences creates an absorbing submicron-thick layer, which exhibits both electrical conductivity and photoconductivity [19,20].…”

Electro-optically tunable transmission grating was imprinted in potassium lithium tantalate niobate by irreversible spatial patterning of the dielectric constant. While embedded into waveguided architecture, it provides a reliable and versatile building block for opto-electronic circuitry, capable of both active switching and multiplexing. Realization of such a block is critical for fabrication of integrated photonic circuits in electrooptic substrates by means of Refractive Index Engineering by fast ion implantation.

Electrically controlled absorption was observed in a slab waveguide, fabricated in a potassium lithium tantalate niobate substrate by proton implantation, at an energy of E=1.15 MeV and a fluence of 6.1×1016ions/cm2. The implantation created an amorphous layer which acted as the cladding with an adjacent proton doped layer at its bottom. It is suggested that a n-i junction is formed at the interface between the proton layer and the substrate, which is the core of the waveguide. The electrically controlled absorption is attributed to changes in the width of the depletion area of the n-i junction induced by the applied field.
