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.

Nanoporous polymer liquid core waveguides

Gopalakrishnan, Nimi; Christiansen, Mads Brøkner; Ndoni, Sokol; Kristensen, Anders; Sagar, Kaushal Shashikant; Vigild, Martin Etchells

2010 Conference on Lasers and Electro-optics (cleo) and Quantum Electronics and Laser Science Conference (qels) — 2010, pp. 1-2

We demonstrate liquid core waveguides defined by UV to enable selective water infiltration in nanoporous polymers, creating an effective refractive index shift Δn=0.13. The mode confinement and propagation loss in these waveguides are presented.

Di-block co-polymer derived nanoporous polymer liquid core waveguides

Christiansen, Mads Brøkner; Gopalakrishnan, Nimi; Sagar, Kaushal Shashikant; Ndoni, Sokol; Kristensen, Anders

Proceedings of Spie — 2010, Volume 7764, Issue 1, pp. 77640J-6

Nanoporous liquid core waveguides are fabricated by selectively UV modifying a nanoporous polymer. The starting point is a diblock polymer where 1,2-polybutadiene (PB) molecules are bound to PDMS. When the PB is cross linked it self-assembles into PB with a network of 14 nm diameter PDMS filled

Liquid Core Waveguides by UV Modification of Nanoporous Polymer

Christiansen, Mads Brøkner; Gopalakrishnan, Nimi; Sagar, Kaushal Shashikant; Berthold, Anton; Ndoni, Sokol; Kristensen, Anders

Ieee Winter Topicals — 2011, pp. 73-74

Liquid core waveguides are fabricated from a self-assembled nanoporous polymer, with a porosity of 40%. The high porosity results in an effective refractive index of 1.26 for visible light, i.e. below the refractive index of aqueous solutions. However, since the polymer is hydrophobic, fluids
