The dissipative Kerr soliton microcomb provides a promising laser source for wavelength-division multiplexing (WDM) communication systems thanks to its compatibility with chip integration. However, the soliton microcomb commonly suffers from a low-power l
A modified extended-ptychographical-iterative-engine (ePIE) algorithm is proposed to overcome the disadvantages of ePIE technique and reduce the influence of stage hysteresis or backlash error. The exit wave of a rotatable "screen" illuminated by plane
