We present a high-port-count (scalable to 1 times 32) wavelength-selective switch (WSS) using a large scan-angle, high fill-factor, two-axis analog micromirror array in conjunction with a densely packed two-dimensional array of fiber collimators. A partially populated (1 times 9) WSS exhibits a fiber-to-fiber insertion loss of 5.57 plusmn 1.4 dB and an extinction ratio of 51 plusmn 11 dB. The channel spacing is 100 GHz
