Optical signal transmission can be significantly improved by limiting the wavelength of transmitted signals. Fiber Bragg grating (FBG) is a technique widely used in optical communication, sensing, and ...

Unhindered electron flows clear the way for improved communications and intelligence applications. High-temperature superconducting materials discovered only 15 years ago now are enabling signal ...

Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The ...
