Researchers Demonstrate Cost-Effective, Scalable Lithium PICs

Facebook X LinkedIn Email
A joint effort from HyperLight and Harvard University has achieved a technical milestone for lithium niobate photonic integrated circuits (PICs). The work demonstrates lithium niobate PICs' compatibility with mass production technologies. The technology aims to alleviate bottlenecks in data center and telecommunications networks while minimizing energy consumption. The team achieved fabrication on 4- and 6-in. wafers and used deep ultraviolet lithography and smooth and uniform etching to realize 0.27 dB/cm optical propagation loss on wafer scale, allowing efficient light guiding. ...Read full article

    lithium niobate
    A crystalline ferroelectric material used primarily as a substrate and an active medium for thin-film optical modulators and switches. It possesses very high electro-optic and piezoelectric coefficients. LiNbO3.
    wafer
    In the context of electronics and semiconductor manufacturing, a wafer refers to a thin, flat disk or substrate made of a semiconducting material, usually crystalline silicon. Wafers serve as the foundation for the fabrication of integrated circuits (ICs), microelectromechanical systems (MEMS), and other microdevices. Here are key points regarding wafers: Material: Silicon is the most commonly used material for wafer fabrication due to its excellent semiconductor properties, high purity,...
