Teraphysics Breakthrough Technology

 

The First Commercially Viable THz Source

1. Sufficient Power (10’s mW) to provide

a. Spectroscopy from a safe standoff distance

b. Real time video rate imaging from a distance

c. Significant penetration depths

2. Compact (<3 lbs, < 5 inches3)

3. Broad, continuously tunable frequency range

Applications mentioned have not been exploited commercially -they have only been demonstrated in laboratory environments. This has become known as the THz gap. But Why does this gap exist? Because there are no potential commercially viable sources in existence except the Teraphysics devices we present here.  What is a commercially viable source? A source that can meet the requirements for the applications we outlined, or a source providing 10s of mW’s of average power that is compact, and continuously tunable over a broad range of frequencies.

 

 

Survey of Existing THz Sources

Existing THz sources are used primarily for research purposes due to such factors as maturity, cost, size, efficiency and low output power at room temperature. Thus, none of these competing sources have the potential to be commercially viable except the Teraphysics’ suite of sources.

Intellectual Property

It is impossible to apply conventional fabrication techniques and designs that work at microwave frequencies to THz devices where the dimensions are on the order of 10 times smaller. Thus, to enable fabrication of vacuum electronics in the THz regime, we have invented novel components to be compatible with microfabrication. In many cases, we invented the microfabrication methods including techniques to form intricately shaped Chemical vapor deposited, or CVD, diamond structures.

The Spectrum

Over 400 years, many technologies have been created based on the commercial exploitation of the electromagnetic spectrum.

From radio to MRI, discoveries made to effectively harness untapped bands have led to inventions that are central to our daily life.

The Terahertz Gap

This scientifically rich band of frequencies within the electromagnetic spectrum has been virtually devoid of commercial activity due to the difficulty in generating sufficient power.

Typical Terahertz sources are too large, and smaller sources too weak to have any commercial use.
