In this paper, we compare behaviors of two possible descriptions of the sampled signal in the case when the sampling period tends to zero, but remains all the time greater than zero. Note that this is the case we are dealing with in analog-to-digital

Abstract In recent years, numerous efforts have been devoted to exploring innovative micro/nano‐optical devices (MNODs) with reconfigurable functionality, which is highly significant because of the progressively increasing requirements for next‐g

Microwave photonic (MWP) systems are inseparable from conversions of microwave electrical signals into optical signals, and their performances highly depend on the linearity of electro-optic modulators. Thin-film lithium niobate (TFLN) is expected to

Machine learning (ML) and neuromorphic computing have been enforcing problem-solving in many applications. Such approaches found fertile ground in optical communications, a technological field that is very demanding in terms of computational speed an

We propose and demonstrate a type of highly efficient thermally tuned interferometer in lithium niobate on insulator (LNOI) thin film using an air bridge structure. By removing the oxide below the lithium niobate (LN) waveguide, the heat transferred

The trade-offs of using thermo-optical phase shifter in different standard CMOS silicon-on-insulator (SOI) structures (strip and rib waveguides) are studied. Twelve different thermo-optic phase shifters, considering metal and highly doped silicon (bo
