    • Hybrid photonic crystal lasers 

      Liles, Alexandros A.; Bakoz, Andrei P.; Gonzalez-Fernandez, Alfredo; Habruseva, Tatiana; Persheyev, Saydulla; Huyet, Guillaume; Hegarty, Stephen P.; O'Faolain, Liam (IEEE, 2016-08-23) - Conference item
      Energy efficient Wavelength Division Multiplexing (WDM) is the key to satisfying the future bandwidth requirements of datacentres. As the silicon photonics platform is regarded the only technology able to meet the required ...

    • Control of Q-factor in nanobeam cavities on substrate 

      Panettieri, Danilo; O'Faolain, Liam; Grande, Marco (IEEE, 2016-08-23) - Conference item
      In this paper, we demonstrate how to efficiently control the quality factor of silicon nitride nanobeam cavities, grown on a silica substrate and embedded in an upper cladding, by engineering the nanobeam cross-section and ...

    • Disorder driven structural and dielectric properties of silicon substituted strontium titanate 

      Dugu, Sita; Pavunny, Shojan P.; Sharma, Yogesh; Scott, James F.; Katiyar, Ram S. (2015-07-17) - Journal article
      A systematic study on structural, microstructural, optical, dielectric, and electrical properties of phase-pure silicon-modified SrTiO3 polycrystalline electroceramics synthesized using high energy solid state reaction ...

    • Submillimetre wave 3D imaging radar for security applications 

      Robertson, Duncan Alexander; MacFarlane, David Graham; Cassidy, Scott Lindsay; Bryllert, Tomas; Gandini, Erio; Llombart, Nuria (2016-03-31) - Conference paper
      There is ongoing worldwide interest in finding solutions to enhance the security of civilians at airports, borders and high risk public areas in ways which are safe, ethical and streamlined. One promising approach is to ...

    • Efficient single photon collection using a μ-fiber-coupled microcavity 

      Lee, Chang Min; Lim, Hee Jin; Schneider, Christian; Maier, Sebastian; Höfling, Sven; Kamp, Martin; Lee, Yong Hee (IEEE, 2016-01-07) - Conference item
      Efficient single photon collection is demonstrated based on a μ-fiber-coupled photonic crystal cavity. 249 kHz of single photons are detected, and estimated single photon count rate (overall collection efficiency) is 20 ...
