摘要：
Optical crossconnects with large port counts are fast becoming critical components for high-capacity optical transport networks, The free-space micromachined optical snitches (FS-MOS) demonstrated in this letter represent a means of filling this network need by combining the advantages of free-space interconnection with the virtues of integrated optics. Featuring free-rotating hinged micromirrors, the switch overcomes the common drawback of mechanical-type snitches, namely long switching time. Measurements have revealed switching times less than 700 mu s, crosstalk less than -60 dB, extinction ratio greater than 60 dB, negligible polarization-dependent loss, and excellent bit-error-rate (BER) performance.
