Dual‐Band Organic Photodetectors for Dual‐Channel Optical Communications

Laser & Photonics Reviews, 2022
The dual‐band organic photodetectors (OPDs) detect incoming light selectively in two different bands. This work demonstrates a bias‐switchable dual‐band OPD, achieving a fast‐switching speed of over 1000 times per second and a −3 dB cutoff frequency of >

Devices and Fibers for Ultrawideband Optical Communications

Proceedings of the IEEE, 2022
Wavelength-division multiplexing (WDM) has historically enabled the increase in the capacity of optical systems by progressively populating the existing optical bandwidth of erbium-doped fiber amplifiers (EDFAs) in the $C$ -band. Nowadays, the number of
