When an optical pulse train is delivered, two-photon absorption (TPA)-induced pumping causes considerable and quick gain and phase shifts in the carrier reservoir semiconductor optical amplifier ...

Phononic crystals (PnCs) are sophisticated materials distinguished by their periodic arrangement of inclusions, which effectively manipulate the diffusion of elastic and acoustic waves. These ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

Electronic processors are reaching the physical speed ceiling that heralds the era of optical processors. Multifunctional all-optical logic gates (AOLGs) of massively parallel processing are of great ...
