LNOI with Metal Electrode (I)

There is a metal electrode layer (Au, Pt, Al, or other metals) between the SiO2 layer and the LN thin film. An electric field can be applied on the LN thin film between this metal electrode layer and a top electrode layer. Based on piezo-electric effects, ferroelectric domain switching effect, thermal-electric effect, this film has applications on surface acoustic wave devices, memory devices, and sensors, such as high-frequency, high-bandwidth RF filter, low-power, high-speed ferroelectric memory, and high-sensitivity IR detector.

Product Application

The single-crystal lithium niobate thin films, which will be of great interest for developing high-speed, wide-bandwidth, high-density and high-efficiency photonic circuits and electronic devices, are mainly used in the following fields:

  • Integrated optics, such as photonic wires, optical filters,electro-optically tunable micro-ring resonators, and optical detectors. The size of the devices made on our products could be reduced by more than one million times, the integrated level would be  greatly enhanced, the consumption of the power would be lower, the performance would be more stable, meanwhile, the cost would be  greatly reduced.
  • High-density data storage. the capacity of a 3inch piece of lithium tantalate thin film can reach up to 70 Tbit, the equivalent of 100,000 CD’s.
  • Electronic devices and components: surface acoustic wave devices , pyro electric detectors, Terahertz wave generation and propagation etc.
