New Laser Could Speed Telecommunications

Facebook X LinkedIn Email
STANFORD, Calif., Nov. 8 -- Researchers at Stanford University have used an array of coupled photonic crystal nanocavities to develop a new kind of laser that could lead to drastically faster speeds in telecommunications and networking equipment, spectroscopic sensing and optical image processing. Because light can carry huge amounts of data, lasers are vital components in modern communications. But current solid-state laser technologies, used in telecommunications and networking equipment, are fast reaching the limits of their capabilities. Now a new type of solid-state laser developed by...Read full article

    photonic crystals
    Photonic crystals are artificial structures or materials designed to manipulate and control the flow of light in a manner analogous to how semiconductors control the flow of electrons. Photonic crystals are often engineered to have periodic variations in their refractive index, leading to bandgaps that prevent certain wavelengths of light from propagating through the material. These bandgaps are similar in principle to electronic bandgaps in semiconductors. Here are some key points about...
