This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Systematic Design of Slow Light Waveguides

Wang, Fengwen

DTU Mechanical Engineering — 2012

, an optimization formulation is presented to tailor the slope of the dispersion curve. The design robustness is enforced by considering different manufacturing realizations in the optimization procedure. Both free- and fixed-topology (circular-hole based) slow light photonic crystal waveguides are obtained using

Systematic design of loss-engineered slow-light waveguides

Wang, Fengwen; Jensen, Jakob Søndergaard; Mørk, Jesper; Sigmund, Ole

Optical Society of America. Journal A: Optics, Image Science, and Vision — 2012, Volume 29, Issue 12, pp. 2657-2666

This paper employs topology optimization to systematically design free-topology loss-engineered slow-light waveguides with enlarged group index bandwidth product (GBP). The propagation losses of guided modes are evaluated by the imaginary part of eigenvalues in complex band structure calculations
