“…The reported amplifiers mainly operate in the communication band. There is less research on amplifiers in other bands, which can be effectively expanded by doping with different REIs, such as neodymium and thulium 128 . In addition, the problems of optical pumping and local doping of REIs also exist, which can be referred to in the previous discussion on REI-doped microlasers.…”

“…The C-Band is distinctive among frequency bands in optical communication due to its comparatively lower signal attenuation, allowing signals to be transmitted over extended distances with minimized loss. It supports numerous communication channels, facilitating high-capacity data transmission [5]. Additionally, the C-Band exhibits resilience to various interference sources and effectively mitigates nonlinear effects, ensuring consistent and reliable signal propagation [6].…”

The advent of all-optical switches marks a significant milestone in optical communication and signal processing. Unlike traditional switches that rely on optic–electronic conversions, all-optical switches operate purely on optical signals, offering unparalleled speed and efficiency. These switches leverage various optical phenomena, such as interference and nonlinear effects, to control the light flow without needing electronic intermediary steps. This research presents a novel approach to all-optical switching through designing, simulating, and validating a polymer-based 1×2 all-optical switch. This advancement demonstrates the potential for advancing optical circuitry by utilizing organic-inorganic hybrid polymer materials. Incorporating a nonlinear directional coupler (DC) enables phase shifting, providing precise control over switching states. The optimized design, which includes a 5 μm core width to confirm single-mode behavior in both input and output sections, was validated using the beam propagation method (BPM). The results highlight an impressive switching capability, with a 5π/6 phase difference between the MZI and DC. The device exhibits minimal excess loss and crosstalk within the C-Band wavelength range (1.53 µm to 1.565 µm). These findings significantly contribute to advancing optical circuitry and communication networks by emphasizing the potential for high-performance optical switching.
