“…Our new design is given in Figure 12 , where we also deploy multiple 2 × 2 crossovers (blue squares here). This diagram is a highly modified version of the monochromatic 6 × 6 utilizing MRRs presented in [ 53 ], where one modification is the replacement of MRRs with our four-color crossbars. If we visualize this as a 24 × 24 router, then the number of active and passive components employed to accomplish the wavelength routing (48 and 9, respectively) is relatively small.…”

In this work, we demonstrate a compact toolkit of inverse-designed, topologically optimized silicon photonic devices that are arranged in a “plug-and-play” fashion to realize many different photonic integrated circuits, both passive and active, each with a small footprint. The silicon-on-insulator 1550-nm toolkit contains a 2 × 2 3-dB splitter/combiner, a 2 × 2 waveguide crossover, and a 2 × 2 all-forward add–drop resonator. The resonator can become a 2 × 2 electro-optical crossbar switch by means of the thermo-optical effect, phase-change cladding, or free-carrier injection. For each of the ten circuits demonstrated in this work, the toolkit of photonic devices enables the compact circuit to achieve low insertion loss and low crosstalk. By adopting the sophisticated inverse-design approach, the design structure, shape, and sizing of each individual device can be made more flexible to better suit the architecture of the greater circuit. For a compact architecture, we present a unified, parallel waveguide circuit framework into which the devices are designed to fit seamlessly, thus enabling low-complexity circuit design.

Optical networking is fast evolving towards the applications of the Software-defined Networking (SDN) paradigm down to the (Wavelength-division Multiplexing) WDM transport layer for cost-effective and flexible infrastructure management. Optical SDN requires each network element's software abstraction to enable full control by the centralized network controller. Nowadays, modern network elements, especially photonic switching systems, are developed by exploiting the fast-emerging technology of Photonic Integrated Circuit (PIC) that consists of complex fabrics of elementary units that can be driven individually using a large set of elementary controls. In this work, we focus on modeling the elementary control states of the topological structures behind PIC N×N switches under a fully blind approach based on Machine Learning (ML) techniques. The ML agent's training and testing datasets are obtained synthetically by software simulation of the photonic switch structure. The proposed technique's scalability and accuracy are validated by considering different dimensions N and applying it to two different switching topologies: the Honey-Comb Rearrangeable Optical Switch and the Beneš network. Excellent results in terms of prediction of the control states are achieved for both of the considered topologies.

“…Because of the benefits of Mach-Zehnder interferometer switches over microring resonator switches, such as wide connection bandwidth and high thermal tolerance, researchers have paid attention to the design of optical routers by using these elements [14][15][16][17]. Routers in this classification have been of great notices to researchers, and in this part, the most important ones in the network on the 2-D and 3-D chips that have been presented in recent years are investigated [17][18][19][20][21][22][23][24][25][26][27].…”

Due to the increasing number of cores in a chip, electronic networks on chip cannot be an effective solution for using multi-core processors. The use of optical connection technology for networks on 3D chip is an ideal choice recommended in response to delay and reliability. In optical network architecture on 3D chip, 7-port routers are used to data transfer. The structure of the optical routers in the network on the 3D optical chip affects the Performance transmission of the entire network so that the provision of optical router with minimal loss and power consumption is considered by researchers in this domain. In this study, a seven-port Non-blocking optical router based on the Mach Zehnder interferometer optical switch in the network on a 3-D optical chip is presented. This router consists of 18 Mach Zehnder interferometer optical switches that can transfer multiple wavelengths concurrently. To evaluate the proposed 7-port router in the network on the 3D optical chip, the parameters of insertion loss, bandwidth density and power consumption are considered and the simulation results represent that this router decreases the loss as much as possible and improves the use of the wavelength channel comparing to available router and has the ability to transfer 4 wavelengths simultaneously with a wavelength range of 1525-1565 nm and a data transfer rate of 20Gbps for all 42 optical links. So it is useable for optical connection on the chip.
