Chalcogenide Glass-on-Graphene Photonics [PDF]

open access: yes, 2017
Two-dimensional (2-D) materials are of tremendous interest to integrated photonics given their singular optical characteristics spanning light emission, modulation, saturable absorption, and nonlinear optics.

The Photodetector Array Camera and Spectrometer (PACS) on the Herschel Space Observatory [PDF]

open access: yes, 2010
The Photodetector Array Camera and Spectrometer (PACS) is one of the three science instruments on ESA's far infrared and submillimetre observatory. It employs two Ge:Ga photoconductor arrays (stressed and unstressed) with 16x25 pixels, each, and two ...

Reconstruction of photon statistics using low performance photon counters [PDF]

open access: yes, 2006
The output of a photodetector consists of a current pulse whose charge has the statistical distribution of the actual photon numbers convolved with a Bernoulli distribution. Photodetectors are characterized by a nonunit quantum efficiency, i.e.

Amplified Dispersive Fourier-Transform Imaging for Ultrafast Displacement Sensing and Barcode Reading

open access: yes, 2008
Dispersive Fourier transformation is a powerful technique in which the spectrum of an optical pulse is mapped into a time-domain waveform using chromatic dispersion.

Non-Gaussian states for continuous variable quantum computation via Gaussian maps [PDF]

open access: yes, 2006
We investigate non-Gaussian states of light as ancillary inputs for generating nonlinear transformations required for quantum computing with continuous variables. We consider a recent proposal for preparing a cubic phase state, find the exact form of the

Performance analysis of a 2-D time-wavelength OCDMA wavelength-aware receiver with beat noise [PDF]

open access: yes, 2006
The effect of beat noise on two-dimensional time-wavelength optical code-division multiple-access systems utilising wavelength-aware receivers is examined. A derivation of a general formula for the bit error probability taking into consideration multiple

CMOS-compatible graphene photodetector covering all optical communication bands

open access: yes, 2013
Optical interconnects are becoming attractive alternatives to electrical wiring in intra- and inter-chip communication links. Particularly, the integration with silicon complementary metal-oxide-semiconductor (CMOS) technology has received considerable ...

Terahertz detection schemes based on sequential multi-photon absorption [PDF]

open access: yes, 2006
We present modeling and simulation of prototypical multi bound state quantum well infrared photodetectors and show that such a detection design may overcome the problems arising when the operation frequency is pushed down into the far infrared spectral ...
