Purpose Scleral cross-linking (SXL) with a photosensitizer and light is a potential strategy to mechanically reinforce the sclera and prevent progressive axial elongation responsible for severe myopia. Current approaches for light delivery to the sclera are cumbersome, do not provide uniform illumination, and only treat a limited area of sclera. To overcome these challenges, we developed flexib...

A theoretical analysis of electromagnetic forces on neutral particles in a hollow waveguide is presented. We show that the effective scattering cross section of a very small (Rayleigh) particle can be strongly modified inside a waveguide. The coupling of the scattered dipolar field with the waveguide modes induces a resonant enhanced backscattering state of the scatterer-guide system close to t...

We report an experimental investigation of the nonlinear optical properties of nanoporous silicon optical waveguides measured at 1550 nm. The nonlinear properties including two-photon absorption, self-phase modulation, free-carrier absorption and free-carrier plasma dispersion are characterized and compared with similar measurements conducted on a conventional silicon-on-insulator ridge wavegui...

This letter presents a high-gain 32 × 32-element full corporate-feed array antenna using simplified assembly of only two split blocks. is made possible by new feeding configuration which eliminates the cavity-backed layer used in conventional designs. E-plane T-junctions, as well single-ridge waveguide output structure, are network to reduce its size. helps realize one-to-one corresponding exci...

Lithium niobate (LiNbO3, LN) channel and ridge waveguides have been successfully fabricated by He ion implantation, which has energy of 500 keV fluence 1.5×1016 ions/cm2 is combined with lithography the precise diamond dicing technique. The refractive index profile annealed LN planar waveguide was reconstructed. propagation loss a width 10 µm that widths 25 15 were investigated end-face couplin...

We report the successful integration on silicon of small footprint, low-threshold electrically pumped edge-emitting lasers by a new approach incorporating microcleaving technology to produce 6m-thick platelet lasers with cleaved facets, microscale pick. and place assembly to position them on the substrate, and diaphragm pressure solder bonding to attach/connect them permanently in place. InP-ba...
