In this paper, we studied a series of high-speed photodetectors (PD) with different super-
lattice interlayer periods and the scale of the effective area to examine their communication …

Nowadays, optical systems play an important role in communications. Dual depletion PIN
photodiodes are common devices that can operate in different optical bands, depending on …

First principles calculations based on density functional theory (DFT) were performed to
investigate the structural, electronic, optical and mechanical properties of pristine GaAs …

The thickness of the pin photodiode's p and n contacts, as well as the width of the
semiconductor device, affect the conductivity performance of the diode. In this study, the …

The selection of an optimal photodetector area is closely linked to the attainment of higher
data rates in optical wireless communication receivers. If the photodetector area is too large …

The advent of 6G communication promises a transformative leap in wireless connectivity,
ushering in an era of unprecedented data rates, ultra-low latency, and pervasive …

In the last two decades, quantum well (QW) lasers have been used for a wide range of
applications at wavelengths spanning on a very large domain and based on various …
