An optical communication link is proposed for high speed point-to-point data transmission. The incorporates both fiber and wireless technologies. Kramer-Kronig coherent detection used due to its component implementation simplicity. Spatial multiplexing, via a multi-core followed by link, wavelength division multiplexing allow the efficient exploitation of all available degrees freedom. signal-t...

In this paper, we study the performance of the multiuser detection in a direct sequence optical code division multiple access (DS-OCDMA) system using novel periodic optical encoder applied to fiber-to-the-X (FTTX) passive optical network (PONs). The performance of our system is analyzed in a synchronous network using multilevel periodic codes (ML-PC) with a conventional receiver model and the r...

We demonstrate the first asynchronous 2x2 optical packet switch capable of synchronizing, buffering, and forwarding 10 Gb/s packets generated from independent transmitters with better than 99% packet recovery measured using a burst mode receiver. ©2010 Optical Society of America OCIS codes: (060.1810) Buffers, couplers, routers, switches, and multiplexers; (230.4480) Optical amplifiers

The nonlinear interaction between amplified spontaneous emission noise and copropagating signal in a dispersive optical fiber is investigated both theoretically and experimentally. A transfer matrix formulation is used to solve the nonlinear propagation equation. A continuous wave (CW) input optical signal format isolates the effect of modulation instability (MI) from the signal self-phase modu...

We report on experimental demonstration of a digital coherent detection link fully based on vertical cavity surface emitting lasers (VCSELs) for the transmitter as well as for the local oscillator light source at the receiver side. We demonstrate operation at 5 Gbps at a 1550 nm wavelength with record receiver sensitivity of -36 dBm after transmission over 40 km standard single mode fiber. Digi...

In an optical multiple-access system, overall system throughput efficiency and significant implementation costreduction would be achieved if many users could access a common optical channel at any time without control among users. Recently one such scheme, an optical orthogonal code division multipleaccess system (OOCDMA), was introduced by Salehi et al. 111-[6] for the case of no noise. In thi...

In this paper, synchronization of chaotic oscillations in semiconductor lasers by optical injection in a transmitter-receiver configuration is studied numerically. A chaotic signal is generated from a semiconductor laser with optical feedback in the transmitter and is injected into the receiver laser without optical feedback. We examined the conditions of chaotic synchronization in the system. ...

To transfer high speed data streams, a line of sight (LOS) broadband free space optical (FSO) communication link has been designed between two private local LANs located at an aerial distance of about 2 km. A laser diode (LD) – avalanche photodiode (APD) combination operating at 1550nm is used to work as an optical trans-receiver system while an Erbium-doped optical amplifier (EDFA) is used to ...
