III–V-on-lithium-niobate balanced photodetector enabled by direct wafer bonding for optical computing

Balanced photodetectors (BPDs) reject common-mode laser intensity noise while preserving the differential signal, making them an essential receiver building block for coherent optical links and for emerging coherent optical-computing architectures that require signed (bipolar) photocurrent accumulation. Integrating suc...
