Low coherent light interferometry requires broad bandwidth light sources to achieve high axial resolution.
Time series analysis of low-energy electron and high-energy proton cosmic ray fluxes, both measured on the Ulysses spacecraft, shows that they are quite coherent in some frequency bands in the ener
We experimentally demonstrate transmission of 6 mode-multiplexed 20-GbdQPSK signals over 1200 km of coupled-core fiber (CCF).
We experimentally demonstrate transmission of 6 mode-multiplexed 20-Gbd-QPSK signals over 1200 km of three-core microstructured fiber (3C-MSF).
Underwater acoustic communication link performance is investigated under strong time-frequency variation.
We demonstrate asymmetric 10 Gbit/s upstream - 100 Gbit/s downstream per wavelength WDM/TDM PON using hybrid silicon lasers as local oscillator and upstream transmitter.
From distributed acoustic sensing (DAS) measurements over deployed multi-core fiber (MCF), we discuss several signal processing options to enhance the sensing sensitivity, namely core combination a
We developed a Michelson-type cavity to achieve coherent combining of two quantum-cascade lasers, emitting at around 4.5 mu m.
The transient intensity of resonant secondary emission from GaAs quantum wells is coherently controlled by means of excitation with two phase-locked pulses.
We demonstrate the first operation of a tapered laser diode array in an external Talbot cavity. The in-phase supermode is selected by tilting the reflected wave.
