Changing Frequency Speeds Phosphor Light Emission

Facebook X LinkedIn Email
A technique for controlling light from phosphors at very high speeds could overcome the materials' slow optical performance, potentially enabling their use in optical communications. Phosphors are common light emitters used in light bulbs, LEDs and elsewhere. While they are extremely efficient, they can't be turned on and off very quickly, which has essentially prohibited their use in applications where rapid optical modulation is required. Using phase-change materials, researchers from Brown and Harvard universities have found a way to modulate light from phosphor emitters...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: ...
