A simple scheme of switchable dual-wavelength passively mode-locked fiber laser is demonstrated.The laser can be fiexibly switched among different mode-locked s
We introduce an instrument for single wavelength measurement of phase retardation based on the laser feedback phenomenon.A method of multi-wavelength conversion
A method to measure the end-output coupling efficiencies between silicon wire waveguides (SWWs) and optical fibers is proposed and demonstrated.The end-output c
Hydrogen is produced by direct dissociation of water vapor,i.e.,splitting water molecules by the electrons in water plasma at low pressure (< 10 50 Torr) using m
InAs quantum dot (QD) lasers have attracted much attention in recent years as they have exhibited extraordinary performance,including low threshold current dens
