“…While current multiplexing techniques (WDM and OTDM) are highly suited to long-haul networks, their requirements of high precision wavelength-stabilization techniques and strict synchronization control limit their overall flexibility and scalability in Local Area Networks (LAN's) and Fibre to the Home (FTTH) networks [6]. In comparison, Optical Code Division Multiple Access OCDMA provides several unique advantages such as asynchronous transmission, soft capacity on demand, and quality of service control [7].…”

This paper investigates the use of a Two-Photon Absorption photodetector for high speed processing of ultrashort optical pulses in advanced photonic communication systems. Specifically the paper describes how the Two-Photon Absorption photodetector maybe employed for chromatic dispersion monitoring in high-speed, wavelength division multiplexed networks, and also for reducing multiple access interference noise in an optical code division multiplexed system.

“…The current multiplexing schemes used in optical networks are wavelength division multiplexing (WDM) and optical time division multiplexing (OTDM). These formats however, require precision wavelength-stabilisation techniques and strict synchronisation between users which reduces network flexibility and scalability [1]. An alternative multiplexing format for local access networks is optical code division multiplexing (OCDM).…”

The authors present a simulation model and results for a four user OCDMA system operating at an overall data rate of 4 Gb/s (4 x 1 Gb/s). The work presents the novel use of a nonlinear detector based on TPA for simultaneous thresholding and detection in an OCDMA system. The detection of the decoded optical signal is also performed using a linear (PIN) detector separately. It is demonstrated that the use of the nonlinear detector can improve the power penalty associated with the transition from a single user system to a four user system by approximately 8.5 dB in comparison to the same system using a linear detector. These results are in good agreement with experimental results already taken.

Abstract-We demonstrate the application of a uniform Bragg grating as a dynamically reconfigurable phase encoder-decoder for optical systems. Precise discrete phase modulation between chips is obtained simply by heating segments along the grating with fine resistive wires. Its reliability to generate and recognize various phase code sequences is demonstrated in a 16-chip 20-Gchip/s quaternary phase-shift keying coherent optical code-division multiple access experiment. The bit-error-rate response is also included to highlight its performance.
