Special Issue Information
Dear Colleagues,
Over the last few years, photonic technologies have experienced a number of dramatic technical advances, tackling the development of high-performance, low-footprint, and price-competitive solutions, which makes it nowadays a key enabling technology in optical networks. This research field not only embraces the classical communication systems but also enables the practical implementation of quantum cryptographic protocols over optical networks. From a classical perspective, the design and fabrication of lasers, high-speed optical modulators for high-order modulation formats, compact and fast coherent receivers, and nonlinear waveguides for phase-sensitive and -insensitive amplification are major photonic technological achievements, allowing the extensive deployment of optical networks.
Moreover, recently, quantum cryptographic systems have been using photonic technologies to boost the successful laboratory experiments in this research field to practical and real-world implementations. In practice, this comprises the integration of bulky optical components on photonic chips, allowing for the generation, manipulation, and detection of different degrees of freedom of individual photons or weak coherent states. Such capabilities require the design and fabrication of devices for quantum state generation, linear and non-linear manipulation of the light, and detection of nonclassical light on a single platform. This is a major achievement considering the integration of several different optical components into a unique chip, which leads to a considerable reduction in the insertion losses and to a unique phase stabilization when compared with bulk optical devices.
Consequently, this Special Issue aims to highlight the recent progress and trends in photonic technologies with applications in optical communications, ranging from classical to quantum domains. This issue will accept high-quality manuscripts reporting original research results and survey articles of exceptional merit, and it will present the readers of this journal with the most recent outcomes and trends in this fundamental research area.
