What type of light does the processor-on-a-chip developed by researchers at RMIT respond to?

The processor-on-a-chip developed by researchers at RMIT responds specifically to visible light. This characteristic is significant as visible light falls within a specific range of wavelengths that can be harnessed for various applications, particularly in photonics and optical computing. The ability to respond to visible light allows for enhanced data processing capabilities and efficient power use, taking advantage of the properties of light that are conducive to high-speed data transfer.

The focus on visible light can also imply a direct application in environments where light can be manipulated and used for intricate tasks in computing. Other types of light, such as infrared and ultraviolet, have different properties and often require different materials and technologies to harness effectively.
