Title:
PHOTONIC CRYSTAL ALL-OPTICAL OR TRANSFORMATION LOGIC GATE
Document Type and Number:
WIPO Patent Application WO/2016/095853
Kind Code:
A9
Abstract:
A photonic crystal all-optical OR transformation logic gate consisting of one optical switch unit (01), one photonic crystal structural unit (02), one reference light source (03), one wave-absorbing load (04), and one D trigger unit (05). Two system signal input terminals (11 and 12) of the optical switch unit (01) respectively are connected to logic signal X1 and logic signal X2. The reference light source (03) is connected to a reference light input terminal (13) of the optical switch unit (01). Three intermediate signal output terminals (14, 15, and 16) of the optical switch unit (01) respectively are connected to two intermediate signal input terminals (21 and 22) of the photonic crystal structural unit (02) and to the wave-absorbing load (04). Clock control signal CP is connected via an input terminal of one T-junction waveguide respectively to a clock signal CP input terminal of the optical switch unit (01) and to a clock signal input terminal (51) of the D trigger unit (05). An output terminal (24) of the photonic crystal structural unit (02) is connected to a D signal input terminal (52) of the D trigger unit (05). The logic gate has a compact structure, fast computing speed, and great anti-interference capability and can easily implement integration with other optical logic elements.
