Optimization of intensity-modulation/direct-detection optical key distribution under passive eavesdropping
Konrad Banaszek, Michal Jachura, Piotr Kolenderski +1
We analyze theoretically optimal operation of an optical key distribution (OKD) link based on fine intensity modulation of an optical signal transmitted over an attenuating channel…
Sub-Rayleigh characterization of a binary source by spatially demultiplexed coherent detection
Chandan Datta, Yink Loong Len, Karol Łukanowski +2
We investigate theoretically coherent detection implemented simultaneously on a set of mutually orthogonal spatial modes in the image plane as a method to characterize properties o…
Complete characterization of weak, ultrashort near-UV pulses by spectral interferometry
Marcin Kacprowicz, Wojciech Wasilewski, Konrad Banaszek
We present a method for a complete characterization of a femtosecond ultraviolet pulse when a fundamental near-infrared beam is also available. Our approach relies on generation of…
Blind dispersion compensation for optical coherence tomography
Konrad Banaszek, Aleksandr S. Radunsky, Ian A. Walmsley
We propose a numerical method for compensating dispersion effects in optical coherence tomography that does not require a priori knowledge of dispersive properties of the sample. T…
Maximum likelihood estimation of photon number distribution from homodyne statistics
Konrad Banaszek
We present a method for reconstructing the photon number distribution from the homodyne statistics based on maximization of the likelihood function derived from the exact statistic…
Accuracy of Sampling Quantum Phase Space in Photon Counting Experiment
Konrad Banaszek, Krzysztof Wodkiewicz
We study the accuracy of determining the phase space quasidistribution of a single quantized light mode by a photon counting experiment. We derive an exact analytical formula for t…
Quantum Interference in Three Photon Down Conversion
Konrad Banaszek, Peter L. Knight
We study degenerate three photon down conversion as a potential scheme for generating nonclassical states of light which exhibit clear signatures of phase space interference. The W…
