摘要:

在線性光學范疇下，光學超構材料等人工結構材料的出現與發展使得人們在控制光與物質的相互作用方面擁有更多自由度。例如，利用人工設計的功能單元可在亞波長尺度對光的振幅、相位和偏振進行靈活有效的調控，從而實現超透鏡、負折射、隱身衣等新奇光學效應。通過調控超構材料中光的幾何相位、局域電磁增強等物理機制，可實現光與物質相互作用的顯著增強，為實現非線性微納光學光源及其應用開啟了新的大門。圍繞近年來光學超構材料在光學頻率轉換、超快光開關與光調制、以及非線性相位調控等方面的研究進展進行了總結，并對非線性光學超構材料在未來應用中的前景和所面臨的挑戰進行了展望。

Abstract:

In linear optics, the emergence and development of artificial materials such as photonic metamaterials provide more degree of freedom to control light�瞞atter interactions. For example, the artificial meta�瞐toms can be used to flexibly and effectively control the amplitude, phase and polarization of light at subwavelength scales. Thus, some novel optical phenomena, such as superlens, negative refraction, and invisible cloak, have been achieved. By controlling the geometric phase of light and local electromagnetic enhancement in metamaterials, to achieve significant enhancement of light�瞞atter interactions, people opens a new door for realizing nonlinear micro/nano light sources and their applications. In this review, the recent research progresses of functionalities of photonic metamaterials such as optical frequency conversion, ultrafast optical switching and modulation, and nonlinear phase control are summarized. We also overview the future applications and challenges of the nonlinear photonic metamaterials.
