Abstract

We present a novel terahertz spectroscopy principle by using incoherent light from a super luminescent diode for terahertz cross-correlation spectroscopy. The combless nature of this light source leads to a truly continuous terahertz spectrum. We demonstrate the possibility to influence the terahertz spectral bandwidth of the system by changing the bandwidth of different bandpass filters in the system. Depending on the employed bandpass filter we achieve peak dynamic ranges of 60 dB or a terahertz spectral width of about 1.7 THz. The applicability of the measurement system to spectroscopic terahertz measurement tasks is demonstrated.

Figures (6)

Fig. 1
Fig. 1 Experimental setup: The output of the superluminescent diode (SLD) is optionally bandpass filtered (BP) and amplified by an EDFA. Afterwards, the light is sent to a standard TDS-like setup consisting of a beam splitter (50:50), delay section, terahertz receiver (Rx) and emitter (Tx) as well as reflective terahertz optics. Photomixers for CW terahertz generation and detection are used.
Fig. 2
Fig. 2 (a) Optical spectrum of the plain SLD (without the optional bandpass or EDFA). (b) The obtained terahertz cross-correlation signal and (c) the achieved mean dynamic range. The isolated peak in the delay domain already indicates the spectral continuity in the terahertz range. A peak dynamic range of 30 dB at 100 GHz and a bandwidth of 1.3 THz are achieved.
Fig. 3
Fig. 3 Comparison of the optical spectra ((a) and (b)) and the delay-dependent terahertz cross-correlation signal ((c) and (d)) when using the setup with a SLD and a multimode laser diode (MMLD), each in combination with the same bandpass filter and EDFA. In contrast to the multimode laser diode source, a truly isolated cross-correlation maximum is observable when using the SLD. This behavior results from the continuous optical spectrum provided by the SLD.
Fig. 4
Fig. 4 Influence of the bandpass width (a) on the dynamic range and bandwidth of the recorded terahertz spectrum (b). A tradeoff between dynamic range at low frequencies and bandwidth can be found.
Fig. 5
Fig. 5 Demonstration of the applicability of the presented approach to spectroscopic measurement tasks. The well-known terahertz simulants para-aminobenzoic acid (PABA, shown in (a)) and α-Lactose monohydrate (b) were measured with the SLD-drivensetup and are compared to the spectra acquired with a standard TDS system. The terahertz beam path was not purged in the SLD-driven setup, so artefacts from water vapor absorptions are present. Within the limited bandwidth, the spectral features are consistent.
Fig. 6
Fig. 6 Comparison of a HITRAN-based simulation of a terahertz spectrum with water-vapor absorption and the spectrum of the SLD-driven CCS system employing a highly accurate delay unit. The differing slopes and absolute amplitudes of the spectra are due to the systems characteristics. The agreement of absolute frequencies as well as the linewidths of the absorption features demonstrate the applicability to gas spectroscopy.
