Polarization bistable VCSELs for optical buffers

摘要

We demonstrated ultrafas all-optical 1-bit memory operation using a polarization bistable VCSEL in a 980-nm range. A 1-bit data signal was arbitrarily sampled and memorized from the 2⁶-1-bit 20-Gb/s PRBS RZ data signals and 6-bit 40-Gb/s NRZ data signals for the first time. Results in the present paper show the high potential of all-optical flip-flop memories based on polarization bistable VCSELs for use in ultrafast all-optical future networks.
