Carbon nanotubes (CNTs) are almost ideal one-dimensional (1D) nanoobjects with outstanding mechanical, electrical, optical and many other properties which are inherent to them both in the form of individual nanoobjects and in the form of various arrays of CNTs. Recently CNTs are recognized as very promising materials for nano-optics, including nanoantennas, nano-rectennas, plasmonics, nanophotonics, optoelectronics, luminescence, light and terahertz radiation, cold field emission, as well as building blocks for metamaterials, metasurfaces, and nanofluids. Many efforts currently is directed to creating CNT based devices for emitting single photons, generating and detecting THz, tunnel resonant diodes, field-effect transistors etc. In this issue, both single CNT nanodevices and phenomena associated with various CNT arrays are being intensively studied. But both for the fundamental study of CNTs and for applications in all these areas of research, it is often required to work with an individual CNT. So it is critically important to select CNTs and control their placement in the desired structures and architectures in the installation or device. The report provides a brief overview of the results of studies of CNTs based structures in nanophotonics, nanoplasmonics, nanooptics, etc. and shows the expanding prospects of these studies using mechanical nanomanipulation with CNTs. The latest experiments carried out by the authors are cited as examples of the creation of CNT metasurfaces and plasmonic CNT nanodevices generating THz radiation. [ABSTRACT FROM AUTHOR]
