• • The device achieves a photocurrent dissymmetry factor (g_ph) dynamically tunable up to -0.06 under positive bias, enabling hardware-level synaptic weight adjustment for enhanced image contrast.
• • Under negative bias, the device operates as a highly sensitive CPL detector, enabling efficient chiroptical signal acquisition and imaging for cancer cell samples.
• • In OCNN-based cancer detection, CPL detection accuracy reaches 83%, approaching the theoretical 87% and outperforming natural light detection at 65%.
• • The dual-mode operation (negative bias for detection, positive bias for synaptic processing) integrates sensing and computation in a single hardware platform, reducing signal transmission losses and improving processing efficiency.
