Using this method, IISC team were able to up-convert infrared light of wavelength around 1550nm to 622nm visible light. “This process is coherent – the properties of the input beam are ...

Much higher frequencies in the near-infrared and visible regions can be obtained in many types of semiconductor lasers or LEDs that exploit a direct energy gap in a semiconductor. The situation ...

Terahertz technology is a field of science and technology that focuses on the electromagnetic waves within the terahertz frequency range. This range falls between microwave and infrared frequencies on ...
