Abstract
An all-optical NAND logic device derived from the negative nonlinear absorption effect has been demonstrated in erbium-doped aluminosilicate glass using 1510-1550 nm laser diodes. The reversed-phase transmitted waveforms were observed at modulation frequencies from 0.2 kHz to 1.0 GHz. The device has a novel possibility for expanding the capacity of optical networks and computers
