Title: Characterization of the nonlinear THz focus for 2D THz spectroscopy

We present a sensitive imaging method capable of the selective characterization of the nonlinear THz beam profile, providing a direct handle to optimizeχ(3)light-matter interactions that are critical to two-dimensional (2D) THz spectroscopies. In particular, this method facilitates the development of experimentally challenging 2D THz spectroscopies with multiple THz emitters, which enables direct investigations of fast picosecond dynamics in liquids and solids that are challenging in single-emitter 2D THz spectroscopic setups.

  1. Abstract

    The terahertz (THz) region of the electromagnetic spectrum spans the gap between optics and electronics and has historically suffered from a paucity of optoelectronic devices, in large part because of inadequate optical materials that function in this spectral range. 2D materials, including graphene and a growing family of related van der Waals materials, have been shown to exhibit unusual optical and electrical properties that can enable diverse new applications in the THz regime. In this review, some of the unusual properties of 2D materials that make them promising for THz applications are explained, the recent work in the field of 2D THz optoelectronics is summarized, and the challenges and opportunities that await this promising new field are outlined.

  2. We present an experimental and theoretical comparison of two different scattering-type scanning near-field optical microscopy (s-SNOM) based techniques in the terahertz regime; nanoscale reflection-type terahertz time-domain spectroscopy (THz nanoscopy) and nanoscale laser terahertz emission microscopy, or laser terahertz emission nanoscopy (LTEN). We show that complementary information regarding a material’s charge carriers can be gained from these techniques when employed back-to-back. For the specific case of THz nanoscopy and LTEN imaging performed on a lightly p-doped InAs sample, we were able to record waveforms with detector signal components demodulated up to the 6thand the 10thharmonic of the tip oscillation frequency, and measure a THz near-field confinement down to 11 nm. A computational approach for determining the spatial confinement of the enhanced electric field in the near-field region of the conductive probe is presented, which manifests an effective “tip sharpening” in the case of nanoscale LTEN due to the alternative geometry and optical nonlinearity of the THz generation mechanism. Finally, we demonstrate the utility of the finite dipole model (FDM) in predicting the broadband scattered THz electric field, and present the first use of this model for predicting a near-field response from LTEN.

  3. We demonstrate a 2D radar system for the THz region using a leaky parallel-plate waveguide, which can support real-time object tracking. The system can track a target within 200 ms with an accuracy of 1 mm in range and 1.4° in angle. Because the system is based on broadband excitation, it can locate multiple objects simultaneously. The broadband excitation also enables sensing of objects for which there is no direct line-of-sight path to the waveguide, via detection of a non-line-of-sight path.

  4. Abstract

    Development of terahertz (THz) sources, detectors, and optical components has been an active area of research across the globe. The interest in THz optoelectronics is driven by the various applications they have enabled, such as ultrawide‐band communication systems, air‐ and space‐borne astronomy, atmospheric monitoring, small‐scale radar, airport security scanners, ultrafast nanodevices, and biomedical imaging and sensing. Here, the aim is to provide a comprehensive review of THz bandpass metamaterials focusing on several areas. First, the design fundamentals and geometrical patterns of THz bandpass metamaterials are summarized. Second, fabrication methods of THz bandpass metamaterials are reviewed, including typical micro‐ and nanofabrication techniques and laser micromachining techniques. More importantly, different engineering methods are reviewed for tuning and modulation of the THz transmission resonance for these metamaterials. Both passive and active modulation methods are included in this discussion; the passive method involves changes in the geometrical pattern of the filter material, and the active method performs in situ modulation of properties by applying an external physical field. Finally, the potential applications and prospects for future research of THz bandpass metamaterials are discussed.

  5. •Terahertz(THz) radiation is nonionizing is therefore harmless to live organisms, as opposed to higher energy radiation, such as x-rays and UV rays. THz low scattering characteristic, as compared to optical rays, and strong absorption by water makes THz useful for imaging organic tissue. • In a Lumpectomy procedure, a tumor is removed from a predetermined area. In most cases, a surgeon will often remove a larger amount of tissue to ensure that all of the cancer is removed however this can extend the patient's recovery period and it does not guarantee that all the cancerous tissue was removed.. • Using the THz Jets Transmission (Tx) Imaging method the goal will be to allow a surgeon to better assess the margins of the excised tissue using higher THz resolution images. • This method is done by transmitting a THz signal through a Teflon sphere, then through the sample, and finally to the receiver on the other side. • Teflon spheres have the ability to filter out the lower terahertz frequencies which then have the potential to produce high-resolution images.
