研制了一种用于产生可调谐毫米波信号的单片集成光子源。该光源由14个有源元件组成，即半导体激光器、放大器和光电探测器，全部集成在3 mm（2）InP芯片上。在85 GHz和120 GHz之间的范围内的外差信号与高达-10 dBm的输出功率已经成功地产生。通过将集成激光器光学注入锁定到外部光学梳状源，已经产生了频率>100 GHz的高光谱纯度信号，在与载波的偏移大于10 kHz时实现了低于-90 dBc/Hz的相位噪声谱密度。(C)2014年美国光学学会
A monolithically integrated photonic source for tuneable mm-wave signal generation has been fabricated. The source consists of 14 active components, i.e. semiconductor lasers, amplifiers and photodetectors, all integrated on a 3 mm(2) InP chip. Heterodyne signals in the range between 85 GHz and 120 GHz with up to -10 dBm output power have been successfully generated. By optically injection locking the integrated lasers to an external optical comb source, high-spectral-purity signals at frequencies >100 GHz have been generated, with phase noise spectral density below -90 dBc/Hz being achieved at offsets from the carrier greater than 10 kHz.
