dc.subject.otherThe physical limitation of conventional CMOS transistors miniaturization and the consequent downfall of Moore’s Law have motivated an ongoing pursuit for emerging technologies to aid the development of computational systems able to support the demands of deep learning, big data, internet-of-things (IoT), autonomous driving, datacenters, cryptocurrencies, wearable systems, neuromorphic computing, and many other applications
dc.subject.otherLow power consumption, high speed of data processing, and low energy dissipation are the main desirable features for the new generation of computers

local.description.resumoThis paper presents and demonstrates the three logic processing levels based on complementary photonic crystal logic devices through photonic integrated circuit modeling. We accomplished a set of logic circuits including AND, OR, NAND, NOR, XOR, FAN-OUT, HALF ADDER, and FULL ADDER based on photonic crystal slab platforms. Furthermore, we achieved efficient all-optical logic circuits with contrast ratios as high as 5.5 dB, demonstrated in our simulation results, guaranteeing well-defined output power values for logic representations; a clock-rate up to 2 GHz; and an operating wavelength at λ ≈ 1550 nm. Thus, we can now switch up for high computing abstraction levels to build photonic integrated circuits rather than isolated gates or devices.
