Published in 2020 at "Chinese Physics B"

DOI: 10.1088/1674-1056/abb232

Abstract: Broadband nonlinear frequency conversions of optical waves are widely employed in multiple areas of optics and photonics. However, the broadening of conversion bandwidth is often at a cost of reduction in efficiency, which may induce… read more here.

Published in 2020 at "Journal of Lightwave Technology"

DOI: 10.1109/jlt.2020.3012899

Abstract: Silica waveguides are often etched by reactive ion etch (RIE) processes. These processes can leave residual topography that can increase optical loss. We investigated the relation between optical loss and various RIE etch. A wet… read more here.

Published in 2021 at "Journal of Computational and Nonlinear Dynamics"

DOI: 10.1115/1.4052572

Abstract: This study investigates the dispersive properties of ridge waves that travel circumferentially around piezoelectric circular ridge waveguides and investigates their resonant modes. Based on the variable separation method and Hamilton's principle, the displacement of ridge… read more here.

Published in 2017 at "Optics express"

DOI: 10.1364/oe.25.019872

Abstract: We report on characterization of ridge waveguides fabricated in KTP (KTiOPO4) by use of diamond-blade dicing and Rb/Ba ion exchange. The waveguides were prepared in substrates that have their z-axis in the surface plane, perpendicular… read more here.
