SUBJECTemonstration of Smallsat Networks (Success)

*secure transmission established*

Our latest discovery, from the Demonstration of Smallsat Networks (DSN) research operation, turned out to be a great success.

The team of researchers led by Me and Specialist agent John Plerton have successfully demonstrated a perfect connection between the swarm of the cubesats, which in turn developed into a superconducting heterodyne receiver with an unprecedented high sensitivity at 4,7 THz in frequency or 63 micrometers in wavelength. The so called super-terahertz heterodyne receiver is able to operate at the exact frequency that is needed to enable the long range cubesats.

This is very good news for Us since we need to study the lines from different astronomic sources to trace star and planet formation and galactic evolution. It is also an important milestone in the development of the technology for the other departments of the Liberty Security Force.

The heterodyne receiver can convert a (high-frequency) signal from space into a lower frequency without losing any information. This mixing of frequencies makes the reception clearer and the signal from space can be amplified better. The heterodyne receiver can offer line detection with a nearly quantum noise limited sensitivity and an unparalleled high spectral resolution. The new superconducting heterodyne receiver is based on a novel solid-state terahertz quantum cascade laser to generate the local signal that is to be mixed with the signal from space (local oscillator, operating at 4,7 THz). A superconducting hot electron bolometer is used as a mixing detector..

A terahertz quantum cascade laser (QCL) is actually a tiny semiconductor chip that is based on a repeated stack of semiconductor multiple quantum well heterostructures, where laser emission is achieved through the use of intersubband transitions. Although a QCL has been demonstrated as a local oscillator in the Kuskokwim.Bay lab before, it is the first time that the QCL is applied at 4,7 THz with an exact targeting frequency. The new QCL is based on a so-called third-order distributed feedback grating design. The grating has a double purpose in realizing both controllable single-frequency emission and a good output beam.

The key results were obtained at Kuskokwim.Bay lab by the group of young scientists from the Department of RD&A. This joint effort was coordinated by Charles Manson and John Palerton.
