Abstract
An apparatus embedded with one or more terahertz transceivers is described. The one or more terahertz transceivers based on at least one optical source is provided to facilitate wireless communication in the apparatus, where the apparatus is embedded with one or more planar antennas. The transceiver operates in terahertz and may be coupled to two different antennas, one for transmission and the other for reception.
Claims8
An apparatus communicating wirelessly with a remote device, the apparatus comprising:
- an antenna set;
- one or more terahertz transceivers coupled to the antenna set to exchange signals with the remote device in one or more predefined frequency bands, wherein each of the terahertz transceivers comprises:
- two optical sources generating two respective optical beams at two different frequencies;
- a photo mixer for generating or detecting terahertz (THz) radiation, wherein the two optical beams from the optical sources are directed onto a photoconductive material, a generated terahertz output signal from the photoconductive material is amplified and radiated as the terahertz radiation when a voltage bias is applied across the photoconductive material, or the photoconductive material generates a time-varying current when a terahertz signal is incident thereon, wherein the current is amplified and processed to extract information from the terahertz signal.
