Optical signal processing offers significant advantages in terms of speed (data rate and bandwidth) and is generally much more energy-efficient than electrical signal processing. Furthermore, optical signal transmission involves less loss, which is why high-speed fiber-optic communication networks form the “backbone” of the internet. In addition to these benefits, optical oscillators (lasers and frequency combs) have fundamentally superior spectral properties compared to their electronic counterparts. Conversely, electronics are highly cost-efficient, enable sophisticated signal processing and use extremely small processing elements (transistors), as well as being programmable by means of software. Currently, optical and electronic circuits tend to be separate components within a system, with optical circuits containing only a few components. However, in recent years, photonic integration technologies such as silicon photonics, indium phosphide, silicon nitride and thin-film lithium niobate technology have advanced significantly. Photonic integration technology enables large numbers of nano-scale optical devices to be combined with complex nano-scale electronics. Consequently, complex optical signal processing can be combined with analogue electronics, digital processors, memory and software. Miniaturized electronic-photonic systems can be integrated onto a single chip or onto a few chips within a single package. Photonic integration therefore allows for miniaturized optics and the close proximity of optics and electronics, reducing energy consumption and size, as well as enabling programmable optics and higher optical system complexity at low cost. These new possibilities break up the paradigm of separate optical and electronic signal processing domains and make it necessary to fundamentally rethink how signal processing algorithms, signal processors, communication networks and sensors should be optimally realized in order to fully exploit the potential of integrated nanophotonic/nanoelectronic systems.
