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.

Spontaneous Emission rate Alteration in Photonic Crystal Waveguides and Photonic Crystal Microavitites

Søndergaard, Thomas

Conference Proceedings — 1999

Spontaneous emission in a number of two-dimentional photonic crystals relative to a homogeneous dielectric is modelled using the fermi Golden rule and the position-dependent photon density of states. Futhermore, numerical results will be presented for the rate of spontaneous emission in waveguides

Spontaneous emission in two-dimensional photonic crystal microcavities

Søndergaard, Thomas

I E E E Journal of Quantum Electronics — 2000, Volume 36, Issue 4, pp. 450-457

The properties of the radiation field in a two-dimensional photonic crystal with and without a microcavity introduced are investigated through the concept of the position-dependent photon density of states. The position-dependent rate of spontaneous radiative decay for a two-level atom with random

Suppression of spontaneous emission for two-dimensional GaAs photonic crystal microcavities

Søndergaard, Thomas; Broeng, Jes; Bjarklev, Anders Overgaard

Summaries of Papers Presented at the Quantum Electronics and Laser Science Conference, 1999. Qels '99. Technical Digest — 1999, pp. 252,253

Summary form only given. Spontaneous emission represents a loss mechanism that fundamentally limits the performance of semiconductor lasers. The rate of spontaneous emission may, however, be controlled by a new class of periodic dielectric structures known as photonic crystals. Although
