To realise the thin-film optical devices, we used an approach in which devices were first fabricated
onto a bulk surface and then subsequently sliced from the parent crystal . Devices prepared in this way can be subsequently bonded to a variety of substrates.The process starts by fabricating a conventional mode converter on a surface of a 0.5 mm-thick LiNbO3 wafer. The bulk device, similar to that first described by Alferness, consists of a titanium-indiffused waveguide with a pair of electrodes . The 3.3 mm-wide straight lines in photo-resist are patterned on a commercially available Z-cut LiNbO3 wafer by a laser-direct-writing system.
