Dynamic Simulation of Optical MEM Switches
... For simplicity, we simulate only a single input switching to either the cross or bar state throughout this paper. Both output states are seen in Figure 1, represented by the solid and dashed arrows, respectively. The mirror fabrication and positioning can be achieved in a variety of ways. For exampl ...

Efficient yellow-green light generation at 561 nm by frequency
... the laser was collimated with a 30× (NA ∼ 0.50) ARcoated aspheric lens and then coupled into the PPLN waveguide using a 40× (NA ∼ 0.55) AR-coated aspheric lens with ∼50% laser-to-waveguide coupling efficiency. A half-wave plate was used to adjust the polarization for optimal SHG in the PPLN crystal. ...
