Some embodiments include a solid-state device structure that includes a first photodiode and a second photodiode that share a common anode region. Bias voltages applied to the first photodiode and/or the second photodiode may be used to control the thicknesses of depletion regions of the photodiodes and/or a common anode region to vary the spectral response of the photodetector. Thickness of the depletion regions and/or the common anode region may be controlled based on resistance between multiple contacts of the common anode region and/or capacitance of the depletion regions. Embodiments include control circuits and methods for determining spectral characteristics of incident light using the variable spectral response photodetector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Solid-state photodetector with a spectral response of the generated photocurrent is controlled by an applied bias voltage","description":"A solid-state photodetector with variable spectral response that can produce a narrow or wide response spectrum of incident light.
