  • Patent number: 11329239
    Abstract: The present invention relates to a bias-switchable spectral response high performance PD with multi-mode detection, e.g., dual-mode photoresponses in NIR and visible light ranges. The dual-mode PD has the absorber/spacer type components in its active layer, e.g., a tri-layer configuration of absorber-1 (absorber-1 absorbs the electromagnetic wave of the first wavelength comprising visible light)/optical spacer/absorber-2 (absorber-2 absorbs the electromagnetic wave of the second wavelength comprising IR light). In the presence of IR light, photocurrent generates in the IR light absorbing layer under a reverse bias. In the presence of visible light, photocurrent generates in the visible light absorbing layer under a forward bias. A bias-switchable spectral response PD offers an attractive option for applications in environmental pollution, bio, medical, agricultural, automotive, fishery, food, wellness and security monitoring, detection and imaging in two or different or multiple distinct bands.
