Abstract: The present disclosure relates systems and methods for tissue remodeling, that ameliorate fat deposits by disrupting adipocytes through low-temperature extended treatment time approaches, in conjunction with selective treatment and/or localized cooling of the treatment site to prevent or minimize damage to non-target tissues.

Abstract: Planar waveguide devices are described which function as elements of a soliton transmission communications system operating at a selected central wavelength. These devices have at least one optical channel waveguide whose core has a refractive index and dielectric constant with a dependence on the optical signal intensity which can balance a negative dispersion in the waveguide at dimensions compatible with monomode transmission of the selected central wavelength. It is a property of such a waveguide that if the input is an optical soliton, the output will also be a soliton. Such circuits are useful at the input and output of a soliton transmitting fiber as part of a high bit-rate (broadband) communications system.
