| Abstract | Optical solitons mediated by cascading of quadratic nonlinearities constitute an active area of research. Interest is driven by the new phenomena that are uncovered and by their potential applications in light beam and pulse manipulation schemes, including cavity and laser systems containing quadratic nonlinear crystals. Quadratic solitons form by the mutual trapping between the multiple waves that parametrically interact through the crystal. When only one of the involved frequencies is input into the crystal, efficient soliton formation at moderate light intensities can only be achieved in a narrow-band of phase mismatches. The bandshape, bandwidth and achievable maximum depend on the set-up considered, and on the input light power. In this paper we show that both the efficiency and the bandwidth, of quadratic soliton excitation can be importantly enhanced by simultaneous frequency-doubling and linear amplification of the fundamental frequency input signal. Such a scheme is realized in self-frequency-doubling optical amplifiers. We focus on spatial solitons in frequency-doubling planar waveguides, but the analysis can be extended to bulk geometries and to temporal solitons. |

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.
