Double tungstate lasers: From bulk toward on-chip integrated waveguide devices [PDF]

open access: yes, 2007
It has been recognized that the monoclinic double tungstates $KY{(WO_4)}_2$, $KGd{(WO_4)}_2$, and $KLu{(WO_4)}_2$ possess a high potential as rare-earth-ion-doped solid-state laser materials, partly due to the high absorption and emission cross sections ...

Broadband and compact ridge substrate-integrated waveguides

open access: yesIET Microwaves, Antennas & Propagation, 2010
A novel class of substrate-integrated waveguides (SIWs) is presented, based on the concept of the classical ridge rectangular waveguide, which permits the design of broadband, compact and low-loss integrated components and interconnects. Two configurations are proposed.

Optomechanical coupling in photonic crystal supported nanomechanical waveguides

open access: yes, 2009
We report enhanced optomechanical coupling by embedding a nano-mechanical beam resonator within an optical race-track resonator. Precise control of the mechanical resonator is achieved by clamping the beam between two low-loss photonic crystal waveguide ...
