To enable high resolution terahertz ... wafer in a specific pattern. When a terahertz beam passes through the wafer, a computer can reconstruct an image of the object based on the pattern of ...

Humans typically blink 4 times per second, equivalent to a frequency of 4 Hz. Blinking at a rate of 1 billion times per second, or 1 GHz, is not possible for a human being. But this is the current ...

Emission is then obtained at the difference frequency of the lasers, and this can be engineered to fall in the terahertz range ... dehydration behaviour, as high-quality spectra from many points ...

Pulses of femtosecond length from the pump laser (left) generate on-chip electric pulses in the terahertz frequency range. With the right laser, the information is read out again.

Among researchers, this is called the terahertz gap. In recent years, it was discovered that light sources in this frequency band can be applied to a wide range of areas such as ultra-high-speed ...

University of Ottawa researchers enhance THz wave frequency conversion in graphene, paving the way for advanced wireless communication and signal processing.
