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 >
