| Abstract | Negative-index (negative phase) metamaterials (NIMs) form a novel class of electromagnetic media that promises revolutionary breakthroughs in photonics [1]. A significant progress has been achieved recently in the design of bulk multilayer negative-index plasmonic structures [2–3]. The majority of NIMs realized to date consist of metal dielectric nanostructures that have highly controllable magnetic and dielectric responses. The problem, however, is that these structures have losses that are difficult to avoid, especially in the visible range of frequencies. The losses originate from a number of sources. Irrespective of their origin, losses constitute a major hurdle to the practical realization of the unique optical applications of these structures. Therefore, developing efficient loss-compensating techniques is of paramount importance. Herein, we explore the feasibility of the developing of such techniques making use the nonlinear-optical (NLO) response of the NIMs. Nonlinear optics in the NIMs remains so far a less-developed branch of optics. On a fundamental level, the NLO response of nanostructured metamaterials is not completely understood or characterized, and cannot be predicted effectively to date. Nevertheless, the fact of the local-field enhanced nonlinearities attributed to the plasmonic nanostructures is well established and some rough estimates of their magnitude can be done. The feasibility of crafting NIMs with strong NLO responses have been demonstrated in [4]. Unlike natural positive-index materials, the energy flow and the phase velocity are counter-directed in NIMs, which determines their extraordinary linear and NLO propagation properties. Counterintuitive properties of nonlinear propagation processes in NIMs, such as three-wave mixing (TWM) optical parametric amplification (OPA), second harmonic generation and changes in the optical bistability, which are in a stark contrast with their counterparts in natural materials, were shown in [5]. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
