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.
We present extensive numerical studies on the determination of coherent wavelength-division multiplexing (WDM) crosstalk penalties for ultradense wavelength-division multiplexed (DWDM) systems, foc
While today's WDM optical networks are mostly based on 10 Gbit/s data, modulated according to the nonreturn-to-zero (NRZ) format, networks at 40 Gbit/s and beyond will likely use more complex modul
Optical transmission systems have seen their performance (system capacity and system reach) drastically improved in the last 15 years by using new technologies such as wide band optical amplificati
The tolerance to PMD is measured with and without polarization multiplexing at 10 Gbauds based on QPSK format.
