Abstract:

Integrated photonics has experienced rapid development over the past two decades due to its compatibility with CMOS manufacturing processes, enabling the large-scale production of optical devices with high density, high yield, and low cost. Silicon nitride, as an emerging integrated photonic platform within the silicon material family combines the beneficial properties of a wide transparency range covering visible to mid-IR, a moderately high refractive index and semiconductor mass manufacturing compatibility. Most importantly, it can achieve low loss and high confinement simultaneously. Here, we will focus on exploiting low loss Si3N4 and provide a brief overview of exploring alumna platform for near UV wavelength.
