WebbThe challenge for CW systems, on the other hand, is to achieve sufficient THz power. Photoconductive antennas (PCAs) work well in pulsed systems with high peak power at a moderate repetition rate. However, they have up to now had severe limitations as photomixer emitters in CW operation. Using LT-GaAs photomixers, THz power of 0.2 µW … Webb12 apr. 2024 · “We have used an optical fibre-coupled femtosecond laser, a voice coil-driven corner mirror with a position sensor and InGaAs/InAlAs photoconductive antennas for THz generation and detection ...
Hybrid Perovskite Terahertz Photoconductive Antenna
Webb1 juni 2024 · This SPG sub-THz emitter integrated with a broadband rounded bow-tie antenna is measured to have a maximum sub-THz emission power of 5.4 nW (−52.7 dBm) at 145 GHz with only 3 mW input light power. We also simulate and analyze the influence of the antenna on the radiation spectrum of the SPG sub-THz emitter.
