“…[1][2][3][5][6][7][8][9] Optical devices are also lightweight, compact, in expensive to manufacture, and more facile with stored data than magnetic materials. In view of these desirable features, several techniques have been reported to implement various arithmetic, 6,10,11 algebraic, 12-14 logic, 7,15,16 and image operations 17,18 in the optical domain. In the last few years, a nonlinear optical material-based all-optical switching mechanism 4,7,8,11,13,[19][20][21] proved its validity as one such promising technique.…”
