4inch 6inch X-cut LN 400nm LiNbO3 thin film on silicon substrate
Introduction
Single crystal lithium niobate (LN) is a very attractive photonic
material with wide transparent window, high refractive index and
large acousto-optic, nonlinear and electro-optic coefficients. The
conversion of bulk LN crystals into thin films of lithium niobate
(TFLN) further enables the preparation of high-performance
integrated photonic devices for classical and quantum applications
such as low-loss waveguides, high-quality micro-resonators,
high-speed modulators, and high-efficiency optical inverters. To
achieve integrated active photonic devices, erbium-doped lithium
niobate films have recently been used to demonstrate microcavity
lasers, waveguide amplifiers, and quantum emitters.
Application
Lithium niobate crystal has excellent piezoelectric, electro-optic,
acousto-optic, nonlinear and other properties. It has a wide range
of uses in military and civilian fields, and the main uses are as
follows:
1. Optical fiber communication---For example, waveguide modulators
used in optical communication, more than 60% of the modulators are
made of lithium niobate. The use of lithium niobate thin film is
one million times smaller than traditional device products, with
high performance, low power consumption and low cost.
2. Electronic devices --- high-quality surface acoustic wave
devices, such as filters, delay lines, etc.
3. Information storage---Tohoku University in Japan has developed
the reading and writing technology, and the information storage
capacity of one piece of the same area is equivalent to the storage
capacity of 100,000 DVDs (70T).
