a Imaging measurement setup with a HKBU mask, where the upper part (e.g., the letters HK) is covered by a 1000 nm bandpass filter, used to demonstrate NIR-I and NIR-II selective detection using a dual-mode narrowband OPD. b Image showing only the BU part of the mask, produced by the OPD operated under a forward bias of 1.0 V. c The entire HKBU image produced by the OPD operated under a reverse bias of −1.0 V.
