We report the design, fabrication and experimental investigation of a spectrally wide-band terahertz spatial light modulator (THz-SLM) based on an array of 768 actuatable mirrors with each having a length of 220 μm and a width of 100 μm. A mirror l

We report the conception, fabrication and characterization of a radar cross section reducing (RCSR) metasurface and its integration into a mesoscopic micromirror-array for terahertz spatial light modulation. The metasurface reduces the specular refle

We present a terahertz-SLM with a frequency working range from 1.0 THz to 2.3 THz. Over the complete frequency range, the spatial modulation contrast exceeds 50% with a peak modulation contrast of 87% at 1.38 THz. The pixels of the SLM consist of mir

2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
We present a new type of terahertz spatial light modulator (THz-SLM) based on an array of large micromirrors. The electrostatically tunable micromirrors spatially modulate terahertz waves in a frequency range from 0.97 THz to 2.28 THz with a peak mod

Radar cross section reducing (RCSR) metasurfaces or coding metasurfaces were primarily designed for normally incident radiation in the past. It is evident that the performance of coding metasurfaces for RCSR can be significantly improved by additiona

Efficient, high speed spatial modulators with predictable performance are a key element in any coded aperture terahertz imaging system. For spectroscopy, the modulators must also provide a broad modulation frequency range. In this study, we numerical
