Title High radiation sensitivity of chiral long period gratings Type Journal Article
Year 2010 Publication IEEE Trans. Nucl. Sci. Abbreviated Journal
Volume 57 Issue 5 Pages 2915 - 2922
Keywords chiral fiber gratings, chiral gratings, chiral LPG, from chiralphotonics
Abstract The radiation sensitivity of chiral long period gratings was investigated for the first time. After a Co-60 gamma dose of 100 kGy they show radiation-induced changes of their transmission dip wavelength of up to 10 nm, which is 100 to 1000 times higher than the radiation-induced wavelength shift of different fiber Bragg grating types. They can therefore be used as radiation sensors down to doses of 10 Gy or even below, but not for accurate dose measurements since the size of the wavelength shift after a certain dose still depends on the radiation dose rate. Chiral gratings made of eight single mode fiber types with differences of their radiation-induced attenuation of several orders of magnitude were investigated in order to look for a correlation between dip wavelength shift and fiber attenuation. However, the dip wavelength curves do not show exactly the same order as the fiber attenuation curves. A theory that can exactly predict all properties of the chiral gratings might enable us to specify from our results an optimized fiber for the production of gratings that can also be used for radiation dosimetry.

Title Chiral diffraction gratings in twisted microstructured fibers Type Journal Article
Year 2010 Publication Optics Letters Abbreviated Journal Opt. Lett.
Volume 35 Issue 3 Pages 342-344
Keywords chiral diffracion gratings, optical fiber gratings, from chiralphotonics
Abstract We observed dips in transmission spectra of uniformly twisted pure-silica microstructured fibers. The spectral positions of the dips and their insensitivity to the surrounding medium are consistent with Bragg diffraction from the helical structure. The reproducibility of the variation of the dip wavelength with temperature up to 1000°C makes the chiral diffraction grating suitable for high-temperature sensing.

Title Improved sensitivity of terahertz detection by GaAs photoconductive antennas excited at 1560 nm Type Journal Article
Year 2010 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 97 Issue Pages 201110 (1-3)
Keywords photoconductive antenna (PCA)
Abstract The terahertz detection by photoconductive antennas (PCAs) based on low-temperature grown (LTG) GaAs with 1.5 μm pulse excitation was revisited. We found that the detection efficiency can be improved by a factor of 10 (20 dB) by reducing the excitation spot size and the gap length of the PCA, maintaining the low noise feature of the PCA on LTG GaAs. As a result, the signal-to-noise ratio higher than 50 dB was obtained at a reasonable incident power of 9.5 mW, suggesting that the scheme is promising for the detection of terahertz waves in practical time domain systems.

Keywords SSPD, SNSPD, erratum
Abstract A calculation error was made in the original publication of this letter. The error was in the calculation of the noise equivalent power (NEP) values for the avalanche photodiode detector (APD) and the superconducting single photon detector (SSPD), the incorrect values were plotted on the right axis in Fig. 1(b). The correct NEP values were calculated with the same equation reported in the original letter and the revised Fig. 1(b) is shown below. The other conclusions of the paper remain unaltered.

Title Spectral dependency of superconducting single photon detectors Type Journal Article
Year 2010 Publication J. Appl. Phys. Abbreviated Journal J. Appl. Phys.
Volume 107 Issue 11 Pages 116103 (1 to 3)
Keywords NbN SSPD, SNSPD
Abstract We investigate the effect of varying both incoming optical wavelength and width of NbN nanowires on the superconducting single photon detectors (SSPD) detection efficiency. The SSPD are current biased close to critical value and temperature fixed at 4.2 K, far from transition. The experimental results are found to verify with a good accuracy predictions based on the “hot spot model,” whose size scales with the absorbed photon energy. With larger optical power inducing multiphoton detection regime, the same scaling law remains valid, up to the three-photon regime. We demonstrate the validity of applying a limited number of measurements and using such a simple model to reasonably predict any SSPD behavior among a collection of nanowire device widths at different photon wavelengths. These results set the basis for designing efficient single photon detectors operating in the infrared (2–5 μm range).

Title Time-resolved spectroscopy of InAsP/InP(001) quantum dots emitting near 2 μm Type Journal Article
Year 2010 Publication Appl. Phys. Lett. Abbreviated Journal Appl. Phys. Lett.
Volume 97 Issue 13 Pages 131907 (1 to 3)
Keywords SSPD, SNSPD, InAsP/InP quantum dots
Abstract By using superconducting single photon detectors, we perform time-resolved characterization of a small ensemble of InAsP/InP quantum dots grown by metal organic vapor phase epitaxy, emitting at wavelengths between 1.6 and 2.2 μm. We demonstrate that alloying phosphorus with InAs allows to shift the emission wavelength toward higher wavelengths, while keeping the high optical quality of these quantum dots at room temperature, with no decrease in their radiative lifetime.

Title Optical NEP in hot-electron nanobolometers Type Journal Article
Year 2010 Publication Abbreviated Journal
Volume Issue Pages 1-7
Keywords HEB, Ti, NEP, femtowatt, SAFARI, SPICA, 650 GHz, 0.65 THz, 460 um, twin slot antenna, SQUID readout
Abstract For the first time, we have measured the optical noise equivalent power (NEP) in titanium (Ti) superconducting hot-electron nanobolometers (nano-HEBs). The bolometers were 2{\mu}mx1{\mu}mx20nm and 1{\mu}mx1{\mu}mx20nm planar antenna-coupled devices. The measurements were done at {\lambda} = 460 {\mu}m using a cryogenic black body radiation source delivering optical power from a fraction of a femtowatt to a few 100s of femtowatts. A record low NEP = 3x10^{-19} W/Hz^{1/2} at 50 mK has been achieved. This sensitivity meets the requirements for SAFARI instrument on the SPICA telescope. The ways for further improvement of the nano-HEB detector sensitivity are discussed.
