“…[195,196] There have been some demonstrations of silicon photonic technologies with multiple waveguide planes, where some of the topological constraints are alleviated. [197,198] In such an architecture routing becomes at the same time easier (fewer problems with crossings) and more difficult (more degrees of freedom and the need to manage the penalties of inter-layer transitions).…”

Silicon Photonics technology is rapidly maturing as a platform for larger‐scale photonic circuits. As a result, the associated design methodologies are also evolving from component‐oriented design to a more circuit‐oriented design flow, that makes abstraction from the very detailed geometry and enables design on a larger scale. In this paper, the state of this emerging photonic circuit design flow and its synergies with electronic design automation (EDA) are reviewed. The design flow from schematic capture, circuit simulation, layout and verification is covered. The similarities and the differences between photonic and electronic design, and the challenges and opportunities that present themselves in the new photonic design landscape, such as variability analysis, photonic‐electronic co‐simulation and compact model definition are discussed.

“…In the last decades, research into photonic integrated circuits (PICs) has intensified and PICs are now emerging as a mature and industrial platform, enabling the integration of active and passive optical components on a single chip in a scalable manner. Prominent PIC platforms, which are being developed to industrial scale, are silicon on insulator (SOI), [1][2][3][4] silicon nitride (SiN), [5][6][7] and indium phosphate (InP) [8][9][10] among others. One DOI: 10.1002/lpor.201700256 of the original PIC platforms that enabled optical fiber communications is lithium niobate (LiNbO 3 ).…”

Lithium niobate on insulator (LNOI) technology is revolutionizing the lithium niobate industry, enabling higher performance, lower cost and entirely new devices and applications. The availability of LNOI wafers has sparked significant interest in the platform for integrated optical applications, as LNOI offers the attractive material properties of lithium niobate, while also offering the stronger optical confinement and a high optical element integration density that has driven the success of more mature silicon and silicon nitride (SiN) photonics platforms. Due to some similarities between LNOI and SiN, established techniques and standards can readily be adapted to the LNOI platform including a significant array of interface approaches, device designs and also heterogeneous integration techniques for laser sources and photodetectors. In this contribution, we review the latest developments in this platform, examine where further development is necessary to achieve more functionalities in LNOI integrated optical circuits and make a few suggestions of interesting applications that could be realized in this platform.

“…Combinations of these technologies can be realistically considered, too, e.g. heterogeneous silicon indium phosphide integration, also known as the hybrid silicon platform [8]; the integration of silicon with silicon nitride [9,10]; or even silicon, silicon nitride, and indium phosphide all together in a single process flow [11,12]. For illustrative purposes, an example of a typical silicon photonic technology is shown in Figure 2.…”

Abstract:Technologies for efficient generation and fast scanning of narrow free-space laser beams find major applications in three-dimensional (3D) imaging and mapping, like Lidar for remote sensing and navigation, and secure free-space optical communications. The ultimate goal for such a system is to reduce its size, weight, and power consumption, so that it can be mounted on, e.g. drones and autonomous cars. Moreover, beam scanning should ideally be done at video frame rates, something that is beyond the capabilities of current opto-mechanical systems. Photonic integrated circuit (PIC) technology holds the promise of achieving low-cost, compact, robust and energy-efficient complex optical systems. PICs integrate, for example, lasers, modulators, detectors, and filters on a single piece of semiconductor, typically silicon or indium phosphide, much like electronic integrated circuits. This technology is maturing fast, driven by highbandwidth communications applications, and mature fabrication facilities. State-of-the-art commercial PICs integrate hundreds of elements, and the integration of thousands of elements has been shown in the laboratory. Over the last few years, there has been a considerable research effort to integrate beam steering systems on a PIC, and various beam steering demonstrators based on optical phased arrays have been realized. Arrays of up to thousands of coherent emitters, including their phase and amplitude control, have been integrated, and various applications have been explored. In this review paper, I will present an overview of the state of the art of this technology and its opportunities, illustrated by recent breakthroughs.
