Multi-component optical solitary waves

We discuss several novel types of multi-component (temporal and spatial) en velope solitary waves that appear in fiber and waveguide nonlinear optics. In particular, we describe multi-channel solitary waves in bit-parallel-wav elength fiber transmission systems for highperformance computer networks, m ulti-color parametric spatial solitary waves due to cascaded nonlinearities of quadratic materials, and quasiperiodic envelope solitons due to quasi-p hase-matching in Fibonacci optical superlattices.
