Abstract :
A novel optical buffer memory with a shift register function is proposed. The buffer memory consists of a two- dimensional array of polarization-bistable vertical-cavity surface-emitting lasers (VCSELs), in which the bit state of the optical signal, "0" or "1" is stored as a lasing linear polarization state of 0 or 90deg. Input data stored as the polarization states of the first VCSEL were transferred to the polarization states of the second VCSEL.
