We present measurements of the quasiparticle lifetime using optical pulses in the temperature range of 50 mK–1 K as well as measurements of the noise spectrum under continuous illumination in planar tantalum resonators. When decreasing the temperat

One of the greatest challenges in the development of future space based instruments for sub-mm astronomy is the fabrication of very sensitive and large detector arrays. Within this context we have started the development of Microwave Kinetic Inductan

We demonstrate the formation of a narrow beam from a long (L??) laser with subwavelength transverse dimensions (wire laser) as an image of the subwavelength laser waveguide formed by a spherical lens. The beam is linearly diverging with the angle det

The possibilities and restrictions for the use of the simple experimental method differential electronic gating (DEG)-developed to determine the shape of repetitive subnanosecond THz pulses in the presence of a large jitter in the trigger signal are

One of the greatest challenges in the development of very sensitive radiation detectors is the fabrication of a large detector array. Within this context we have started the development of Kinetic Inductance Detectors. The heart of each detector cons

We report on a phase locking experiment of a 3.4 THz Quantum Cascade Laser (QCL) by using only room temperature electronics. A super-lattice harmonic mixer was used to produce a bit signal between the QCL signal and the 18th harmonic of a 190 GHz ref

Specific features of radiation structure of terahertz quantum cascade lasers are determined by wire geometry of their waveguides with small and sub-wavelength transverse dimensions and the length much larger than the wavelength. Here we present an ov

We demonstrate an experimental scheme to simultaneously stabilize the frequency and amplitude of a 3.5 THz third-order distributed feedback quantum cascade laser as a local oscillator. The frequency stabilization has been realized using a methanol ab
