Demonstration of 470 GHz Bandwidth Wireless Transmitter Based on Photo-mixer for Simultaneous Transmission of Photonics-generated Signals in All-Band 6G Systems

We experimentally demonstrate a 40-510 GHz all-band wireless transmitter covering the Q-, V-, W-, D- and THz-band communication links simultaneously. This is the first demonstration that a single photo-mixer is used to support simultaneous multiple transmissions over millimeter and terahertz channels.
