“…In 2014, this device was demonstrated to achieve a working speed of 100 Mbps and 10 Gbps by adopting forward-biased p-i-n diodes and reverse-biased p-n junctions to tune the MRRs respectively [67,68]. The structure can also implement XOR/XNOR operations [69] by utilizing the coupled-resonator-induced transparency (CRIT) phenomenon [70], of which the spectra are shown in Fig. 4g and h.…”

Optical directed logic (DL) is a novel logic operation scheme that employs electrical signals as operands to control the working states of optical switches to perform the logic functions. This review first provides an overview of the concept and working principle of DL. The developing trends of DL computing are then discussed in detail, including the fundamental optical DL gates, combinational optical DL operations, reconfigurable logic computing, low power optical logic computing, and programmable photonic network. The concluding remarks provide an outlook on the DL future development and its impacts in optical computing. Graphical Abstract

“…Despite the apparent simplicity of the logical operation AND, OR and XOR, these tasks unveil the main characteristics of the reservoir: the nonlinear transformation of the input and the presence of fading memory [16,[23][24][25]. AND and OR, are linear tasks, and therefore, do not require a nonlinear response for their solution.…”

The nonlinear response of an optical microresonator is used in a time multiplexed reservoir computing neural network. Within a virtual node approach combined with an offline training through ridge regression, we solved linear and nonlinear logic operations. We analyzed the nonlinearity of the microresonator as a memory between bits and/or as a neural activation function. This is made possible by controlling both the distance between bits subject to the logical operation and the number of bits supplied to the ridge regression. We show that the optical microresonator exhibits up to two bits of memory in linear tasks and that it allows solving nonlinear tasks providing both memory and nonlinearity. Finally, we demonstrate that the virtual node approach always requires a comparison of the reservoir's performance with the results obtained by applying the same training process on the input signal.

“…EPDC uses sophisticated electronics to control the circuits while allowing photons to go through their waveguided circuits at the speed of light to process the information [10], [11]. Up to now, most of the demonstrations on the EPDC, including logic gates and functional circuits [11], [12], [14], [16], [23]- [31], can be categorized as optical combinational logic (OCL). Figure 1 shows a typical on-chip EPDC circuit that can cover most of these proposed structures.…”

The recent rapid progress in integrated photonics has catalyzed the development of integrated optical computing in this post-Moore's law era. Electronic-photonic digital computing, as a new paradigm to achieve high-speed and power-efficient computation, has begun to attract attention. In this paper, we systematically investigate the optical sequential logic and pipelining in electronic-photonic computing, which together offer a solution to potential problems in latency and power budget as the size of electronic-photonic computing circuits scales up considerably to achieve much more complex functions. Pipelining and sequential logic open up the possibility of highspeed very-large-scale electronic-photonic digital computing.
