Abstract :
Summary form only given. Clock recovery (CR) is an essential part of any transmission system. In this paper, we propose a new type of optical clock recovery based on an optical PLL, where a SLALOM (Eiselt et al., 1995) acts as an ultrafast phase comparator. The scheme has been demonstrated successfully at bit rates up to 160 Gb/s.
