An emerging class of fiber waveguide structures is being used to increase the functionality of fiber devices, enabling new optical components critical to the performance of next generation lightwave networks. These devices rely on advances in the fabrication of optical fiber waveguides, which go beyond the conventional silica design and fall into two general categories: 1) fibers drawn with modified claddings that include non-silica regions throughout their length, examples include photonic crystal fibers; and 2) local modifications to the waveguide after fabrication, examples include fiber devices that incorporate thin film electrodes integrated into the cladding region for efficient thermal actuation. Design and optimization of these type of complex waveguide devices relies on an assortment of sophisticated and often clumsy modeling tools, including modeling of waveguide properties (e.g. photonic bandgap calculations), heat-flow dynamics in thermally actuated fiber devices, simulations of grating devices using coupled mode equations, and finally, simulations that model systems integration. This talk will review developments of a number of different technologies and discuss some of the key challenges associated with modeling and design. Emphasis will be placed on the underlying physics of the different device structures and systems performance.
