A dual beam photonic wavelength refernce
We present operation of a photonically integrated wavelength reference at 780 nm using a dual beam geometry. The dual beams are generated by a pair of extreme mode converting grating beam expanders that generate a pair of overlapped, counter-propagating ...

EVALUATION OF DUAL SYSTEMS WITH MOMENT-RESISTING FRAME AND SHEAR LINK FRAME \ [PDF]
This paper puts forward a new dual system to dissipate energy and presents its numerical studies. Though moment-resisting frames have a good ductility performance, they suffer low stiffness; as a matter of fact, engineers try to increase the stiffness by
