Abstract
The analysis and optimization of optical devices manufacturing technologies based on carbon nanotubes intended for work in the visible range were carried out. These processes studied in the work have practical application for the deposition of carbon nanotubes and their subsequent use as materials for prototypes of the waveguide and sensor of the visible range. To obtain a layer of carbon nanotubes, a chemical vapor deposition chamber was used. A dense horizontal network of CNTs was grown on silicon wafer by utilizing sandwich type catalyst structure. The growth was carried out with two variable parameters: flow rate and flow duration. Various aspects of the CNTs synthesis, mechanism of CNTs growth and power dependent laser sensing are considered in this article. The remarkable properties of as developed photo detector are its fast response and recovery time with 8% sensitivity.
