چکیده
Our recent results on the demonstration of on-chip mode-division multiplexing functionalities are reviewed, with a special emphasis on the feasibility of nonlinear all-optical signal processing on the silicon-on-insulator (SOI) platform. Mode-selective parametric processes are demonstrated in a 4-mm long SOI waveguide. OCIS codes: (130.3120) Integrated optics devices; (030.4070) Modes; (130.7405) Wavelength conversion devices; (190.4380) Nonlinear optics, four-wave mixing; (060.4230) Multiplexing; (200.4650) Optical interconnects.

متن کاملThe Benefits of Ultrashort Optical Pulses in Optically Interconnected Systems
Many properties of an optically interconnected system can be improved through the use of a modelocked laser. The short pulse duration, high peak power, wide spectral bandwidth, and low timing jitter of such a laser lead to these benefits. Timing advantages include simplified synchronization across large chip areas, receiver latency reduction, and data resynchronization. Lower power dissipation ...
متن کاملDifferent criterions for PAPR reduction methods in OFDM systems and Performance Measurement for such systems
One of the challenging issues in today’s OFDM system which is MCM is to handle high PAPR of the transmitted OFDM signals. The OFDM receiver detection efficiency is very much sensitive to nonlinear devices used in signal processing such as HPA and DAC. The criterion of PAPR reduction is to find methodology which can reduce PAPR drastically and at the same time it can keep reasonably good perform...
متن کاملSpace-frequency coded orthogonal signal-division multiplexing over underwater acoustic channels.
Orthogonal signal-division multiplexing (OSDM) is a newly emerged modulation scheme which provides a generalized framework unifying conventional orthogonal frequency-division multiplexing (OFDM) and single-carrier frequency domain equalization. In this letter, a space-frequency block coding (SFBC) scheme based on OSDM is proposed for time-varying underwater acoustic channels. The receiver proce...
متن کاملSelective Tone Reservation method for PAPR reduction in SFBC-OFDM systems
The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...
