https://doi.org/10.1007/978-3-031-47017-2nly one component of the second-harmonic field is phase matched but this argument is based upon the magnitude of the linear phases only. For a situation in which linear phase matching is absent the nonlinear phases are important and will balance the linear phases. The full vector theory needs to be investigated therefore.

A restriction is that second-order processes only occur in media that do not possess a centre of symmetry. Optical fibres, on the other hand, being made of silica gl

Climate Change in the Lehstenbach Regioncause of the possibility for easier experimental observation. Two basic types of solitons exist in this case: . [., .] and . [., .]. An interesting feature of the spatial case of beam propagation is that it can be extended into two transverse dimensions (2D) [.–.].

Bashkinof the electromagnetic spectrum, so that near-resonant excitation can be achieved, resulting in high nonlinear responses; in addition semiconductors support mature fabrication technologies which can be used to make devices in waveguide form, which can in principle be integrated with laser sources on the same substrate.
