N2 - We present a novel scheme for subharmonic clock recovery from an optical time-division-multiplexing signal using time-domain optical Fourier transformation and a narrowband optical filter. High-resolution 640-Gb/s clock recovery is successfully demonstrated with no pattern dependence. The clock recovery is also applied to a 640-Gb/s differential phase-shift-keying transmission, and error-free performance is achieved over 300 km.
