Special Issue Information

Dear Colleagues,

Compared with traditional optics, integrated optics caused a technological revolution once various optical devices could be integrated on chips with compact size, lower energy consumption, and high stability, solving the deficiencies of traditional optics. Based on the high refractive-index-contrast and CMOS-compatible processing of the silicon-on-insulator material, it has become a quite promising platform for integrated optics, allowing silicon photonics to emerge. Up to now, many functional devices have been developed to solve the issues of electro-optic modulation, wavelength/polarization/mode management, fiber-to-chip coupling, high-capacity transmission, signal processing, photo-electric detection, and others in the field of silicon photonics. Recently, new technologies (e.g., artificial intelligence algorithms) and materials (e.g., 2D materials, phase change materials, ferroelectric materials) have been introduced to silicon photonics to enhance device performance and explore some new applications.

This Special Issue focuses on the state-of-the-art achievements in silicon photonic devices, covering new device structures, new photonic materials, new fabrication techniques and new applications. With the unflagging efforts of the worldwide researchers, we believe silicon photonics will enter a new stage of development with powerful device functions, high integration densities, and cutting-edge applications.

The slowdown of Moore’s law and the existence of the “von Neumann bottleneck” has led to electronic-based computing systems under von Neumann’s architecture being unable to meet the fast-growing demand for artificial intelligence computing. However, all-optical diffractive neural networks provide a possible solution to this challenge. They can outperform conventional silicon-based electronic neural networks due to the significantly higher speed of the propagation of optical signals (≈108 m.s−1) compared to electrical signals (≈105 m.s−1), their parallelism in nature, and their low power consumption. The integrated diffractive deep neural network (ID2NN) uses an on-chip fully passive photonic approach to achieve the functionality of neural networks (matrix–vector operations) and can be fabricated via the CMOS process, which is technologically more amenable to implementing an artificial intelligence processor. In this paper, we present a detailed design framework for the integrated diffractive deep neural network and corresponding silicon-on-insulator integration implementation through Python-based simulations. The performance of our proposed ID2NN was evaluated by solving image classification problems using the MNIST dataset. Full article
