In Geographic Information Science, polynomial methods such as linear estimation and non-polynomial methods including Inverse Distance Weighting and Kriging have been used for elevation data interpolat...
This paper describes a 3D modeling method for wide outdoor environments by integrating stop-and-go and continuous scanning of laser rangefinder. First, range images of an outdoor scene are meas...
A continuously or/and discontinuously tunable LiNbO3 Optical Parametric Oscillator (OPO) with the spectral range of 1.42 - 4.24 um and shifting of 0…12 nm is created and investigated. The OPO resonato...
A continuous-wave fiber optical parametric oscillator with a tunability of 114 nm, a wavelength span of 143 nm and single-longitudinal-mode oscillation is demonstrated. The short-term linewidth of the...
Continuous variable quantum key distribution relies on the transmission of weakly modulated coherent states and the detection of optical field for secure communication. In this talk, we give an overvi...
We implement an experimental continuous variable quantum key distribution system over 24 km of optical fiber that uses discrete signaling and a continuous wave local oscillator. A secure key rate of 3...
Single-shot, amplitude and phase characterization of 160-GHz bandwidth optical wave-forms with 2-μs record lengths using a bandwidth- and time-record scalable technique based on parallelized balanced ...
Constant envelope formats including CPM may reduce the impact of nonlinear impairments arising from intensity variations and the associated nonlinear phase noise. We quantify the advantages of CPM ver...
We report on a CW fiber OPO, whose output wavelength can be tuned over the 1463-1674nm range, by means of a tunable intracavity filter. Over 1W of output power can be extracted at long wavelengths.
In this paper, a continuous wave (cw) spectrometer in the far infrared range is presented. Electromagnetic radiation is generated via photomixing phenomena and covers frequencies between about 50 GH...
Single-longitudinal-mode fiber optical parametric oscillator is realized by resonating independently the signal and idler frequencies in two separate optical cavities, combined with a sub-ring cavity ...
We report operation of a continuous-wave one-pump fibre OPA with net gain between 1447 nm and 1717 nm. We used a 114 m long step-index highly-nonlinear fibre, and 5 W of pump power.
The generation of plasma in cesium vapor excited by cw laser is investigated theoretically. We have developed a computational model which quantitatively explains the laser power dependences of elect...
908 mW of green light at 532 nm were generated by intracavity quasiphase matching in a bulk periodically poled MgO:LiNbO3 (PPMgLN) crystal. A maximum optical-to-optical conversion efficien...
We used the sub-nanometer bandwidth of a bismuth-oxide fiber OPA for demultiplexing 10Gb/s channels 100GHz apart with penalty <2dB. We obtained -20dB of crosstalk, with 2.5W of CW pump power.
