Photonic integrated optical phased arrays and their applications [Invited]
【摘要】 In recent years, optical phased arrays(OPAs) have attracted great interest for their potential applications in light detection and ranging(Li DAR), free-space optical communications(FSOs), holography, and so on. Photonic integrated circuits(PICs)provide solutions for further reducing the size, weight, power, and cost of OPAs. In this paper, we review the recent development of photonic integrated OPAs. We summarize the typical architecture of the integrated OPAs and their performance.We analyze the key components of OPAs and evaluate the figure of merit for OPAs. Various applications in Li DAR, FSO,imaging, biomedical sensing, and specialized beam generation are introduced.
