Abstract :
Wireless data transmission at 10.6 Gb/s on a 94-GHz carrier is achieved using photonic components operating at frequencies less than 18 GHz, including a laser diode, two lithium niobate modulators, and an arrayed waveguide grating. A uni- traveling-carrier photodiode is used to convert the doubly modulated optical signal to a modulated millimeter-wave (mmW) carrier. Two antennas are used to transmit and receive the data-encoded mmW signal. A Schottky-diode detector is used to detect the on-off keyed data on the mmW signal at power levels greater than -20 dBm. MMW wireless signals are measured out to a distance of 800 m.
