A combination of loss properties of Periodic Segmented Waveguides and second order wavelength conversion processes is shown to exhibit features which allow to realize an adjustable optical power limiter using classical integrated optics technologies. Results of numerical simulations are presented to confirm the viability of the proposed approach using input and output power levels in the range ...

Department of Electrical Engineering, Eindhoven University of Technology, P.O. Box 513, 5600 MB Eindhoven, The Netherlands Abstract  It is widely recognized that all-optical packet switched telecommunication nodes require a form of all-optical buffering and synchronization to avoid congestion in the switching matrix . We present a novel all-optical switching concept suitable for these purposes...

Today's high-capacity telecommunication systems are unimaginable without the use of optical fibres and accompanying optical components which are briefly presented in this paper with an accent on the receivers of optical signal. An overview of main characteristics of the key elements and the description of the most popular modulation formats in modern optical systems is shown. Some achievements ...

We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication. Visible and infrared multi-aperture interferometry requires many optical functions (spatial filtering, beam combination, photometric calibration, polarization control) to detect astronomical signals at very high angular resolution. Since ...
