Silicon Photonics In article number 2401718, Jiangbing Du, Ke Xu, and co‐workers show that an optical closed loop based on 3D integrated waveguides can be leveraged for enhanced light‐matter interaction. The enhanced absorption enables high responsivity and large bandwidth for on‐chip photodetectors beyond its cut‐off wavelengths.
