Dendrimer terahertz and nanoPhotonic Integrated Circuit (nPIC©)*
ARP generates high power terahertz radiation from electro-optic dendrimer, a high c(2) nanomaterial. ARP's proprietary design is utilized to produce a few milliwatts of CW terahertz power.
Utilizing this source ARP is producing terahertz spectrometer and other terahertz products. See technical presentations for details.
Also see ARP news on terahertz network: "ARP uses dendrimer based terahertz generation technique via difference frequency method. This technique is different than the so called photomixing where one laser is kept fixed and another laser is temperature tuned to vary the mixing wavelengths. ARP uses a dendrimer based high power source pumped with two diode lasers where the beam is split into two arms: one arm remains stationary while the other arm scans the stationary beam that produces an interferogram, characteristic of the specimen-THz interaction. Up to 30 THz can be generated by ARP method with an average power of ~ 3-4 mW."
ARP technology provides a one-box spectrometer: smaller footprint, higher performance, and cost-effective. ARP’s TeraSpectra is a turn key spectrometer. Time domain measurements can be conducted over a time span of sub-Pico seconds to a few tens of Pico-seconds with a resolution of <100 fs.
