New papers (by Date)[edit]

September 23 (AT). CO2 ablated cavities from Warburton Group in Basel. Development and characterization. [A small mode volume tunable microcavity: Development and characterization]

August 27 (JMS). New PRX from Kae Nemoto and Bill Munro describing a scalable scheme for diamond measurement-based QIP. Needs cavity coupled NVs! [Photonic Architecture for Scalable Quantum Information Processing in Diamond]

August 27 (JMS). ArxiV paper from Igor Aharonovich on novel single emitters in nanodiamond. They're going to send us some! [Study of narrowband single photon emitters in polycrystalline diamond films]

July 22 (JMS). New PRB from Lachlan Rogers and Fedor on electronic properties of SiV- [Electronic structure of the negatively charged silicon-vacancy center in diamond]

Feb 25 (JMS). Recent paper from Mete Atature's group in Cambridge on nanodiamond magnetometry. [Observing bulk diamond spin coherence in high-purity nanodiamonds]

Feb 18 (PRD). Another paper from Mete collaborating with Chrispoh Becher on SiV spin properties. [Optical signatures of silicon-vacancy spins in diamond]

Jan 19 (JMS). Experimental paper by Mahrt group on FIB-milled cavities. [Integrated vertical microcavity using a nano-scale deformation for strong lateral confinement]


Dec 29 (JMS). Diamond 'magnetometry'. A group at the Lawrence Berkeley National Laboratory use ODMR of NV- to detect the spin resonance signatures of other nearby defects. [Optically Detected Cross-Relaxation Spectroscopy of Electron Spins in Diamond]

Dec 27 (JMS). A PRB from April this year by the IBM group showing FDTD models of Fabry Perot microcavities. They compare 'square' cavities with Gaussian shapes and show that the latter can offer higher Q/V ratios. No surprises there then. Still its worth a read. [Vertical microcavities with high Q and strong lateral mode confinement]
