“…However, in a biased condition, more biasing current is required to sustain the gain. As the gain increases with the increase of βint, the output power of the maxima increases, but that of the minima does not change, and hence the extinction ratio increases 40 , 41 . In the unbiased state, βint is high, but in the biased state i.e., in the ON state with a large biasing current, βint is negligibly small.…”

“…So we exploited the attractive frequency encoding techniques for their advantageous aspects of unalternation of the signal even after reflection, refraction, and attenuation in long-haul communication networks 35 – 40 We use the optical signal of frequency “ν1” to encode the binary state “0” and frequency “ν2” to encode the binary state “1.” The basic block diagram of Toffoli gate is shown in Fig. 1, and the frequency-encoded data-based truth table of Toffoli logic gate is shown in Table 1.…”

Bit-error detection and correction is a very important part of a data communication network. In this article, we propose an optical approach to designing an error detection and correction circuit using Hamming code-based frequency encoded binary data and Toffoli gates.Here, the Toffoli gates are made of semiconductor optical amplifiers (SOAs) that work based on the nonlinear polarization rotation property. The characteristics of SOA, including very fast switching action (about 0.01 ns), low power consumption, frequency independent crosspolarization gain in the C-band, cascading property, etc., make the scheme attractive. The frequency encoded data-based proposed scheme will be effective for WDM communication networks. MATLAB simulation results testify to the feasibility of the proposed scheme.

“…Furthermore, advances in these research areas may have immediate technological implications and be of interest to industry. For example: Highly efficient single-photon sources on demand [35], photon-numberresolved detectors [36], and photonic integrated systems including passive power splitters and wavelength filters would have impact in the field of secure quantum communication [37]; The development of switches that operate at few photon levels could drastically mitigate the high energy required for optical communication and computation in supercomputers, and it would also play a major role in the reduction of worldwide energy requirements in information & communication technology (ICT) [38]; Bio-inspired materials such as light-harvesting complexes could open new routes towards efficient photovoltaic cells [39]; New approaches to single-molecule detection and quantum-enhanced measurements will expand sensor capabilities, opening new scenarios particularly within the fields of metrology, security and safety.…”

Nanoscale quantum optics explores quantum phenomena in nanophotonics systems for advancing fundamental knowledge in nano and quantum optics and for harnessing the laws of quantum physics in the development of new photonics-based technologies. Here, we review recent progress in the field with emphasis on four main research areas: Generation, detection, manipulation and storage of quantum states of light at the nanoscale, Nonlinearities and ultrafast processes in nanostructured media, Nanoscale quantum coherence, Cooperative effects, correlations and many-body physics tailored by strongly confined optical fields. The focus is both on basic developments and technological implications, especially for what concerns information and communication technology, sensing and metrology, and energy efficiency.

Scalability is a critical issue for access and aggregation networks as they must support the growth in both the size of data capacity demands and the multiplicity of access points. The number of connected devices, the Internet of Things, is growing to the tens of billions. Prevailing communication paradigms are reaching physical limitations that make continued growth problematic. Challenges are emerging in electronic and optical systems and energy increasingly plays a central role. With the spectral efficiency of optical systems approaching the Shannon limit, increasing parallelism is required to support higher capacities. For electronic systems, as the density and speed increases, the total system energy, thermal density and energy per bit are moving into regimes that become impractical to support-for example requiring single-chip processor powers above the 100 W limit common today. We examine communication network scaling and energy use from the Internet core down to the computer processor core and consider implications for optical networks. Optical switching in data centres is identified as a potential model from which scalable access and aggregation networks for the future Internet, with the application of integrated photonic devices and intelligent hybrid networking, will emerge.
