The objective of this proposal is to develop novel photonic devices and artificial materials-appropriately engineered to display properties not found in nature. A new approach that exploits the complex dielectric permittivity plane in its entirety will be employed. This will be achieved by judiciously controlling both absorption and gain-especially in integrated optical arrangements based on semiconductor wafers. To carry out this task, an interdisciplinary team composed of engineers, physicists, material scientists, and mathematicians with complementary skills and know-how has been assembled. The intellectual merit of this activity is based on very recent developments in optics that make use of space-time reflection. The non-Hermitian potentials involved in such arrangements break the spatial symmetry, thus allowing a wave to distinguish left from right. This leads to non-reciprocal wave behavior in both space and time. The team will investigate: (i) non-reciprocal light propagation in linear and nonlinear non-Hermitian structures as a means to realize compact optical isolators and circulators; (ii) wavefront and energy propagation for on-chip beam deflectors; (iii) non-Hermitian absorbers and amplifiers by manipulating the propagation properties of light; and (iv) unidirectional invisibility induced by non-Hermitian gratings. The broader impact of this work will be on educating students to drive tomorrow?s advancements in photonics. They will be trained in modeling, material growth, device fabrication, and optical characterization and through constant interactions with their peers at the partner institutions. The team will organize workshops to engage the photonics community at large in non-Hermitian optics.

该建议的目的是开发新型的光子设备和人造材料，并符合人造材料，以显示自然界中未发现的特性。将采用一种新的方法来利用复杂的介电介电常数平面。这将通过明智地控制吸收和增益来实现，尤其是基于半导体晶片的集成光学布置。为了执行这项任务，由工程师，物理学家，物质科学家和数学家组成的跨学科团队都以互补的技能和专有技术组成。这项活动的智力优点是基于使用时空反思的光学方面的最新发展。涉及此类布置的非热势打破了空间对称性，从而使波浪可以区分左右。这会导致空间和时间上的非重新磁波行为。该团队将研究：（i）线性和非线性非热结构中的非逆性光传播，作为实现紧凑的光学隔离器和循环器的一种手段； （ii）芯片束偏转器的波前和能量传播； （iii）通过操纵光的传播特性，非热吸收器和放大器； （iv）非热光栅引起的单向隐形性。这项工作的广泛影响将是教育学生明天在光子学上的进步。他们将通过与合作伙伴机构的同龄人的持续互动进行建模，材料增长，设备制造和光学表征的培训。该团队将组织研讨会，以与普通群体社区参与整个非热门光学元素。
