چکیده

A novel MEMS thermopile structure is presented, which consist of linearly arranged pand ntype polysilicon strips instead of the conventional loop-like configuration. It is shown that these devices sense the millimeter wave radiation beyond the infrared. The polarity and frequency dependence of the sensitivity prove that these strips behave as absorbing antennas towards the microwave/millimeter wave radiation. The measured responsitivities to direct heating, infrared radiation, 13 GHz microwave radiation, 100 GHz millimeterwave and THz radiation are presented. © Selection and peer-review under responsibility of FET11 conference organizers and published by Elsevier B.V.

Some properties of a room temperature THz detection array

Detection peculiarities of an un-cooled (room temperature) 8×8 pixel array designed to image broadband THz radiation were investigated. Each pixel consists of a thin conductive film absorber on a dielectric membrane with thermopile temperature readout. It was designed and tested for four combinations of two different types of absorber and thermopile materials. The photo-response profile, determ...

Three-Contact Photoconductive Antenna for Polarization Detection of THz Radiation

For polarization measurement of terahertz (THz) electromagnetic radiation we conventionally have been using a set of wire-grid polarizers. In the THz time domain spectroscopy (TDS) measurements, such a method requires twice of the time-delay scans, which is time consuming and can be the origin of the systematic error caused by the intensity fluctuation of laser. In addition, the efficiency of a...

Spiral Antenna-Coupled Microbridge Structures for THz Application

Bolometer sensor is a good candidate for THz imaging due to its compact system, low cost, and wideband operation. Based on infrared microbolometer structures, two kinds of antenna-coupled microbridge structures are proposed with different spiral antennas: spiral antenna on support layer and spiral antenna with extended legs. Aiming at applications in detection and imaging, simulations are carri...

Detection of up to 20 THz with a low-temperature-grown GaAs photoconductive antenna gated with 15 fs light pulses

The generation and detection of terahertz ~THz! radiation using ultrashort optical pulses has been intensively studied during the last decade. The pulse width of commercially available mode-locked Ti:sapphire lasers is approaching 10 fs. With such ultrashort pulses, a wider detection bandwidth is expected to be possible. Coherent detection of THz radiation based on a photoconductive ~PC! antenn...

Coherent terahertz radiation detection: Direct comparison between free-space electro-optic sampling and antenna detection

We compare the use of free-space electro-optic sampling ~FSEOS! with photoconducting antennas to detect terahertz ~THz! radiation in the range of 0.1–3 THz. For the same average THz power and low-frequency modulation, signal-to-noise ratio and sensitivity are better with antenna detection at frequencies smaller than 3 THz. When the modulation frequency is increased to more than 1 MHz in FSEOS, ...
