Fully-integrated CMOS single photon counter.

Optics express

Tisa S, Tosi A, Zappa F.
PMID: 19532523
Opt Express. 2007 Mar 19;15(6):2873-87. doi: 10.1364/oe.15.002873.

Traditionally, Single Photon Avalanche Diodes (SPADs) are fabricated using dedicated processes that require additional technological steps when compared to standard CMOS. Instead, this paper presents the design of SPADs that attain good performances, by using a standard high-voltage CMOS...

Low-noise low-jitter 32-pixels CMOS single-photon avalanche diodes array for single-photon counting from 300 nm to 900 nm.

The Review of scientific instruments

Scarcella C, Tosi A, Villa F, Tisa S, Zappa F.
PMID: 24387425
Rev Sci Instrum. 2013 Dec;84(12):123112. doi: 10.1063/1.4850677.

We developed a single-photon counting multichannel detection system, based on a monolithic linear array of 32 CMOS SPADs (Complementary Metal-Oxide-Semiconductor Single-Photon Avalanche Diodes). All channels achieve a timing resolution of 100 ps (full-width at half maximum) and a photon...

The origin of long-period lattice spacings observed in iron-carbide nanowires encapsulated by multiwall carbon nanotubes.

Microscopy and microanalysis : the official journal of Microscopy Society of America, Microbeam Analysis Society, Microscopical Society of Canada

Boi FS, Mountjoy G, Luklinska Z, Spillane L, Karlsson LS, Wilson RM, Corrias A, Baxendale M.
PMID: 23816334
Microsc Microanal. 2013 Oct;19(5):1298-302. doi: 10.1017/S1431927613001918. Epub 2013 Jul 02.

Structures comprising single-crystal, iron-carbon-based nanowires encapsulated by multiwall carbon nanotubes self-organize on inert substrates exposed to the products of ferrocene pyrolysis at high temperature. The most commonly observed encapsulated phases are Fe₃C, α-Fe, and γ-Fe. The observation of anomalously...

A Functional Role for CREB as a Positive Regulator of Memory Formation and LTP.

Experimental neurobiology

Room temperature continuous wave operation and controlled spontaneous emission in ultrasmall photonic crystal nanolaser.

Optics express

Nozaki K, Kita S, Baba T.
PMID: 19547074
Opt Express. 2007 Jun 11;15(12):7506-14. doi: 10.1364/oe.15.007506.

Photonic crystal slab enables us to form an ultrasmall laser cavity with a modal volume close to the diffraction limit of light. However, the thermal resistance of such nanolasers, as high as 10(6) K/W, has prevented continuous-wave operation at...

Tunable supercontinuum light vector vortex beam generator using a q-plate.

Optics letters

Rumala YS, Milione G, Nguyen TA, Pratavieira S, Hossain Z, Nolan D, Slussarenko S, Karimi E, Marrucci L, Alfano RR.
PMID: 24281515
Opt Lett. 2013 Dec 01;38(23):5083-6. doi: 10.1364/OL.38.005083.

Spatially coherent multicolored optical vector vortex beams were created using a tunable liquid crystal q-plate and a supercontinuum light source. The feasibility of the q-plate as a tunable spectral filter (switch) was demonstrated, and the polarization topology of the...
