RESUMEN
We propose and experimentally demonstrate a low-loss, radio frequency (RF) photonic signal combiner with flat response from 1â GHz to 15â GHz and low group delay variation of 9 ps. The distributed group array photodetector combiner (GAPC) is implemented in a scalable Si photonics platform and has applications in RF photonic systems that rely on combining massive numbers of photonic signals.
