David L. Shenkenberg

Scientists are interested in optoelectronics applications, such as optical memory storage, and in molecular machines that mimic biological molecules, which usually exhibit precision superior to that of man-made devices. These diverse fields may benefit from the fact that a laser can open and close with precision tiny rod-shaped channels made of certain crystals, a discovery made by Nobel laureate Ahmed H. Zewail and members of his laboratory at California Institute of Technology in Pasadena. Using ultrafast electron microscopy, researchers watched as short laser pulses with high fluence...Read full article

    optoelectronics
    Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light and its interactions with different materials. The term "optoelectronics" is a combination of "optics" and "electronics," reflecting the interdisciplinary nature of this field. Optoelectronic devices convert electrical signals into optical signals or vice versa, making them crucial in various technologies. Some key components and applications of optoelectronics include: ...
