Abstract :
In this paper, we review two approaches for serial-to-parallel conversion of asynchronous burst preamble-free optical packets which alleviate these issues in a compact, low-power form. The first is an optoelectronic approach targeted for 10-Gb/s to >40-Gb/s packets, based on an optically clocked transistor array (OCTA). SPC and parallel-to-serial conversion (PSC) (i.e., multiplexing), as well as generation of the clock required for both conversion functions, are achieved with a single, low-power OEIC chip. The second is an all-optical approach that employs optical switching by means of differential spin excitation, for SPC of 40-Gb/s to 1-Tb/s optical packets. Combined with CMOS, these interfaces enable a high-performance, highly scalable approach to optical packet switching
