“…These preliminary studies have shown that for the wavelength range Manuscript of a few millimeters, far infrared radiation with relatively high field amplitudes can be detected by GDDs [5]- [7]. The detection of the far-infrared wave was attributed to the wave giving energy to the plasma itself thereby changing the current through the plasma [4], [5], [7]. It was also shown that the responsivity of a GDD can be changed by changing the polarization of the far-infrared radiation [5].…”

“…The interactions between the gas discharge plasma and EM waves are well defined and have been tested physically, especially in the far-infrared and microwave regions of the spectrum [1], [2]. Room temperature detection in this wavelength range with high sensitivity is still an area of intense study [4]- [7]. Recently, there have been investigations into understanding the effects of microwave and far-infrared radiation on direct current (DC) discharge glows both experimentally and theoretically.…”

“…Recently, there have been investigations into understanding the effects of microwave and far-infrared radiation on direct current (DC) discharge glows both experimentally and theoretically. Here, researchers used low cost neon indicators otherwise known as glow discharge detectors (GDDs) for microwave/submillimeter wave detection [3], [4].

“…Since the frequency of far-infrared radiation is much higher than the frequency of the plasma, the far-infrared radiation can easily propagate through the dc discharge plasma. However, low energetic electrons are made to oscillate by the incoming radiation, and are able to diffuse out of the Faraday dark space and out of the negative glow region [4]. In these regions, electrons can respond to the THz radiation more easily than the ions because of their low masses.…”

Characterization of a Glow Discharge Detector With Terahertz Time Domain Spectroscopy

Recently, there has been much interest in the capability of low cost glow discharge detectors (GDDs) for detection of terahertz radiation. To utilize them in applications such as terahertz imaging these studies have typically focused on the response of the GDD at specific frequencies. To better understand the spectral behavior of glow discharges, we examine the interaction mechanism of GDDs with terahertz radiation using terahertz time domain spectroscopy in a broader range of frequencies between 0.05 and 0.5 THz. Our results show that in addition to terahertz-induced oscillations in the plasma charge density, the structure of the GDD itself plays an important role in the detection mechanism. We observe that by increasing the bias voltage on the gap, not only can we greatly reduce the transmission at a specific frequency, but we can also tune it as well, suggesting that these devices can be used as hybrid plasma filters.Index Terms-Glow discharge detector (GDD), terahertz (THz) spectroscopy, terahertz time domain spectroscopy (THz-TDS), THz detector, hybrid plasma filter.

“…This is a remarkably broad range, spanning six orders of magnitude. Furthermore, neon lamps as GDDs exhibit a wide dynamic range [9], are electronically rugged (can be exposed up to 30 kW of light without damage) [10], and exhibit a relatively low noise equivalent power (NEP) (10 −8 to 10 −12 WHz −1/2 ) [4,5].…”

Terahertz radiation impinging on a lit neon tube causes additional ionization of the encapsulated gas. As a result, the electrical current flowing between the electrodes increases and the glow discharge in the tube brightens. These dual phenomena suggest two distinct modes of terahertz sensing. The electrical mode simply involves measuring the electrical current. The optical mode involves monitoring the brightness of the weakly ionized plasma glow discharge. Here, we directly compare the two detection modes under identical experimental conditions. We measure 0.1-THz radiation modulated at frequencies in the range 0.1-10 kHz, for lamp currents in the range 1-10 mA. We find that electrical detection provides a superior signal-tonoise ratio while optical detection has a faster response. Either method serves as the basis of a compact, robust, and inexpensive room-temperature detector of terahertz radiation.

The terahertz gap (0.1‐10 THz) is an attractive frequency band for new applications. In wireless communication, it can serve as a high capacity link. The lack in use of that gap exists due to a lack of available commercial communications technology systems in that region. We have found that neon indicator lamps or glow discharge detectors (GDD) can be used as simple and very inexpensive detectors in that frequency gap. In modern modulation techniques, the signal phase should be recovered. This article is a proof of concept of detection of quadratic amplitude modulated millimeter‐wave signals by a GDD and photodiode using a heterodyne detection method.
