In March 2019, researchers from the City University of Hong Kong, Harvard, and Nokia Bell Labs developed new on-chip electro-optic modulator made from lithium niobate
. The modulator provides faster data transmissions at lower costs, and is projected to be used in 5G base stations, to facilitate smooth fiber data transmission.
That was before SEAS researchers, led by Marko Loncar, the Tiantsai Lin Professor of Electrical Engineering, developed a technique to fabricate high-performance optical microstructures using lithium niobate
, which has powerful electro-optic properties.

Due to its availability, widespread use, and versatility, lithium niobate
, LiNb[O.sub.3] (LN), is one of the most promising ferroelectric materials, characterized by high Curie temperatures ([T.sub.c] = 1210[degrees]C), band gap ([E.sub.g] = 3.7 eV), and piezoelectric and electro-optical coefficients.
Here, we reported a series of new material [Sr.sub.2-x][Na.sub.x]Nb[O.sub.4] containing Nb[O.sub.4] tetrahedra, which was prepared from sodium niobate
and SrC[O.sub.3] with different ratios under ambient air.
The lithium niobate
(LiNb[O.sub.3], LN) is one of the most attractive materials for these applications due to its high nonlinear and electrooptical coefficients .
A similar behavior was observed for ferroelectric potassium niobate
(KNb[O.sub.3]) nanofibers by Ganeshkumar et al.
