Quadratic solitons as nonlocal solitons.
We show that quadratic solitons are equivalent to solitons of a nonlocal Kerr medium. This provides new physical insight into the properties of quadratic solitons, often believed to be equivalent to solitons of an effective saturable Kerr medium. The nonlocal analogy also allows for analytical solutions and the prediction of bound states of quadratic solitons.
متن کاملQuadratic Solitons: Recent Developments
Multicolor optical solitons mediated by quadratic nonlinearities have been observed experimentally during the last few years in a variety of materials and geometries in a number of laboratories around the world. Today, many of the basic properties of the corresponding soliton families are theoretically well established. Nevertheless, experiments continuously reveal new surprises, and the topic ...
متن کاملOptical solitons in PT -symmetric nonlinear couplers with gain and loss
We study spatial and temporal solitons in the PT symmetric coupler with gain in one waveguide and loss in the other. Stability properties of the highand low-frequency solitons are found to be completely determined by a single combination of the soliton’s amplitude and the gain-loss coefficient of the waveguides. The unstable perturbations of the high-frequency soliton break the symmetry between...
متن کاملEstimation with Quadratic Loss
It has long been customary to measure the adequacy of an estimator by the smallness of its mean squared error. The least squares estimators were studied by Gauss and by other authors later in the nineteenth century. A proof that the best unbiased estimator of a linear function of the means of a set of observed random variables is the least squares estimator was given by Markov [12], a modified ...
متن کاملRegression with quadratic loss
Regression with quadratic loss is another basic problem studied in statistical learning theory. We have a random couple Z = (X ,Y ), where, as before, X is anRd -valued feature vector (or input vector) and Y is the real-valued response (or output). We assume that the unknown joint distribution P = PZ = PX Y of (X ,Y ) belongs to some class P of probability distributions over Rd ×R. The learning...
