Video compression remains a challenging task despite significant advancements in end-to-end optimized deep networks for video coding. This study, inspired by information bottleneck (IB) theory, introduces a novel approach that combines IB theory with

In this chapter, we discuss the possibility of quantum dot (QD) laser and QD semiconductor optical amplifier (SOA) applications in ultra-wideband (UWB) communication systems. We mainly concentrate on novel methods of UWB pulse photonic generation, UW

The design of a 3×1 multimode interference power combiner based on a slot waveguide is proposed for reducing losses. Results show that after light propagation of 9.82 µm the beam combiner efficiency can reach 97.6%.

Liquid crystals (LCs) are organic materials characterized by the intermediate properties between those of an isotropic liquid and a crystal with a long range order. The LCs possess strong anisotropy of their optical and electro-optical properties. In

Today, photonic integrated circuits (PIC) that work with a high-modulation speed (100Gb/s and beyond) are required to use more optical power to overcome the losses. One solution is to use a high-level laser with a hundred milliwatts power. However, f

We investigated theoretically dynamics of a semiconductor optical amplifier (SOA) based on the quantum dot-in-a-well (QDWELL) structure. We modified the QDWELL laser rate equations for the case of SOA and solved the modified equation system numerical

We used the Ludge-Scholl (LS) model of the optically injected quantum dot (QD) in a well (QDWELL) laser and carried out the numerical simulations for the LS rate equation system. We have shown that due to the optical injection, the electron and hole

The peculiarities of a cross-gain modulation (XGM) in quantum-dot semiconductor optical amplifier (QD SOAs) related to the inhomogeneous broadening are theoretically studied. We have solved numerically the electron rate equations for the QD SOA model
