A novel design and fabrication approach for a high fill-factor micro-electro-mechanical system(MEMS) micromirror array-based wavelength-selective switch(WSS) is presented. The WSS is composed of a polarization-independent transmission grating and a high fill-factor micromirror array. The WSS is suc-cessfully demonstrated based on the fabricated high fill-factor micromirror array. Test results show that the polarization-dependent loss(PDL) is less than 0.3 dB and that the insertion loss(IL) of the wavelength channel is about -6 dB. The switching function between the two output ports of WSS is measured. The forward switching time is recorded to be about 0.5 ms,whereas the backward switching time is about 7 ms.
