International topical meeting on microwave photonics (MWP 2000) PY 2000 BP 225 EP 228 DE THz; teraherts communications; terahertz communication channel; photodiode; transmitter AB A photonics-based 120-GHz transmitter has been developed. A photodiode, a planar antenna and a silicon lens were integrated to form a compact millimeter-wave (MMW) emitter. The MMW signal emitted from the transmitter has been detected with a waveguide-mounted Schottky diode. The received power exceeded 100 μW, which is the highest value ever reported for photonic MMW transmitter at frequencies of >100 GHz ER
