The SSD may also include a field programmable gate array (FPGA) operative to perform a comparison of a search sequence with a reference sequence, where the reference sequence is stored in the flash memory. The FPGA may: identify a continuous match of atoms between the search sequence and the reference sequence; divide the search sequence into a left portion of the search sequence that includes atoms before the continuous match of atoms in the search sequence, a center portion of the search sequence that includes the continuous match of atoms in the search sequence, and a right portion of the search sequence that includes atoms after the continuous match of atoms in the search sequence; match the left portion of the search sequence with the reference sequence; and match the right portion of the search sequence with the reference sequence.

Abstract: A passive all optical polarization switch and apparatus and methods for implementing logical operations using the switch is provided. The switch converts a first polarized beam having a polarization angle equals to or nearly equals to ±45 degrees into a beam equal to or nearly equal to the vertical component of the first polarized beam. The switch converts a second polarized beam having a polarization angle equals to or nearly equals to ±45 degrees into a beam equal to or nearly equal to the horizontal component of the second polarized beam. The switch combines the vertical component of the first polarized beam and the horizontal component of the second polarized beam to produce an output polarized beam. The switch is used to implement all optical polarization logic gates.

Abstract: Logical operations are implemented using polarization-based logic level representation. An input polarized beam is split into a first beam and a second beam. The first beam is polarized at a first relative polarization angle and the second beam is polarized at a second relative polarization angle. The ratio of the amplitudes of two perpendicular polarization components of the input polarized beam is one or nearly one and the difference between the first relative polarization angle and the second relative polarization angle is 180 degrees or nearly 180 degrees. The relative polarization angle of the input polarized beam equals or nearly equals either the first relative polarization angle or the second relative polarization angle.
