Optical signal processing towards optical router
Digest of the 9th International Conference on Optical Internet (COIN 2010), 2010We present all-optical wavelength conversion that can be used in the all-optical wavelength routing system. The wavelength conversion is capable of converting the same wavelength using a single semiconductor optical amplifier. Experimental proofs are presented.

Sidelobe reduction in optical signal processing
Applied Optics, 1993A general procedure is introduced for sidelobe and noise reduction in optical or digital signal processing. Specific examples of sidelobe reduction in imaging are presented. It is demonstrated that the new method provides superior spatial resolution to previously proposed sidelobe-reduction techniques.

Optical Signal Processing and Telecommunication Applications
Optical Amplifiers and Their Applications, 2005Optical packet switching has received considerable attention over the last few years. In this paper we discus how optical signal processing can play a role in photonic packet routing. Two examples are given. Firstly we discuss ultrafast wavelength switching at 160 Gbit/s in a single semiconductor optical amplifier. Secondly, an integrated photonic flip-

Several optical configurations for signal processing have been discussed. The ability to format the input signals to enhance the processing ability of the optical system has been emphasized together with the importance of the input transducer. Specific attention has been given to the use of the folded spectrum for high time-bandwidth signal processing ...

Magneto-Optic Signal Processing
Journal of Applied Physics, 1971A modification of the well-known methods for optical processing recorded signals using coherent light and the Fourier-transform properties of lens systems is described, in which the signals are magnetically recorded in a conventional fashion on high-coercivity metallic magnetic films and in which the longitudinal Kerr effect is used to spatially ...

Optical Fiber Delay-Line Signal Processing
IEEE Transactions on Microwave Theory and Techniques, 1984Optical-fiber delay line devices offer great potential1 for the processing of broadband signals due to the large modulation bandwidth and low loss of the optical fiber itself, which for the case of single-mode fiber can have values of the order of 100 GHz-km and fractional dB/km, respectively.

In the early days of optical communications, signal processing was provided electrically. This means that switching and routing of signals was operated in an electrical domain whereas only transmission over large distances was done optically. In order to reduce costs and to increase reliability, signal processing should be carried out in the optical ...

Optical Fibre Signal Processing
SPIE Proceedings, 1984The principle stimulus for fibre optic technology is undoubtably high capacity telecommunications links. However, optical fibre sensors are becoming an increasingly important subject, and it is probable that this will become an important aspect of transducer technology in the none too distant future. It is also conceivable that fibre optics will make a

Optical Signal Processing Devices
1999In the previous chapters we have presented advanced optoelectronic devices which performed a specific task: generation of coherent radiation, modulation, light detection or multi/demultiplexing. In this chapter the perspective is reversed. Namely, we will show that with a few devices one can process a light pulse, i.e.

Signal processing subsystems for optical interconnects
2013 Conference on Lasers and Electro-Optics Pacific Rim (CLEOPR), 2013Progresses in design, realization and management of passive, tunable and reconfigurable silicon photonics circuits are reported. The need for a control layer with suitable probes, control strategies, signal monitoring and actuators is discussed.
