The lifetime of n=1 image-state electrons on stepped on Cu(7 7 5) has been measured as a function of their translational momentum, k∥. At the terrace normal this lifetime is equal to that for flat Cu(1 1 1), i.e. τ=18±2 fs . For motion parallel t

We have fabricated a bicell detector consisting of a single freestanding film of single-crystal lithium niobate (LiNbO/sub 3/) 10-/spl mu/m thick, having two adjacent domains of opposite spontaneous polarization, and hence, two adjacent pyroelectric

Reports on fabrication and characterization of the first zeroth-order half-wave plates of LiNbO/sub 3/ obtained by crystal ion slicing (CIS). Polarization rotation was demonstrated in 10-/spl mu/m-thick freestanding LiNbO/sub 3/ films with 30-dB conv

We report on optical frequency mixing in epitaxial liftoff thin films of single-crystal LiNbO3 integrated onto heterogeneous planar glass platforms. These films are found to have a nonlinear optical response comparable to that of the bulk. Second-har

We report on a large etch selectivity enhancement in the epitaxial liftoff of He+-implanted single-crystal lithium niobate (LiNbO3) films upon rapid thermal annealing. A buried sacrificial layer is formed by ion implantation. Heat treatment is found

We have packaged a rectangular 3 mm x 4 mm, 10-mum-thick Z-cut lithium niobate (LiNbO(3)) film produced by crystal ion slicing (CIS) and evaluated its performance as a pyroelectric optical detector. We justify the difficulty of preparing the film by

We report on the fabrication and chic((2)) measurements of thin ~10-mum -thick films of periodically poled LiNbO(3), obtained by crystal ion slicing. The d(33) optical coefficient in the films is probed by sum-frequency generation with a short-pulse

A normally dark 1×1 switch based on a highly asymmetric Y-branched polymeric waveguide is demonstrated. This device exhibits an attenuation level of 50dB at power-off state and an excess loss of 0.2dB at power-on state.

Crystal ion slicing can fabricate microns-thin-films from bulk, single-crystal metal oxides, which are important materials in optical, microwave, and electrical applications. These thin-films maintain single-crystal properties, which are very difficu

We report on the first 1024×1024 switch designed in a planar lightwave circuit, enabled by the 30% refractive index contrast achievable in our buried-channel polymer waveguides. We present architectures, design considerations, and implementation sch
