Abstract

We present an on-chip LED based on native Si, fabricated in an open foundry CMOS node. This LED has remarkable characteristics such as its sub-wavelength emission area, broad spectrum, high spatial intensity, high bandwidth, and high reproducibility, which make it an ideal light source for various imaging and sensing systems. Two prototypes, a holographic microscope and a LIDAR, are built employing this LED. Our work demonstrates the possibility of integrating monolithic light sources with other photonic and electronic components on a single photonic chip.
