Description

Achieving Compact Photonic Integration With 4-Inch LNOI Wafers

LNOI stands for Lithium Niobate on Insulator, which is a specialized substrate technology used in the field of integrated photonics. LNOI substrates are fabricated by transferring a thin layer of lithium niobate (LiNbO3) crystal onto an insulating substrate, typically silicon dioxide (SiO2) or silicon nitride (Si3N4). This technology offers unique advantages for the development of compact and high-performance photonic devices.

The fabrication of LNOI substrates involves bonding a thin layer of LiNbO3 onto an insulating layer using techniques like wafer bonding or ion-cutting. This results in a structure where LiNbO3 is suspended on a non-conductive substrate, providing electrical isolation and reducing the optical waveguide losses.

Applications of LNOI:

  • Integrated Photonics
  • Optical Communication
  • Sensing and Metrology
  • Quantum Optics
