Hybrid WDM and Optical Spectral Amplitude Coding with Array Waveguide Gratings over Fiber-to-the-Home Network

The hybrid wavelength-division multiplexing and optical code-division multiple-access scheme for EPON (called WDM/OCDMA-EPON) is presented over fiber-to-the-home (FTTH) network. In this study, each ONU (optical network unit) group is assigned the maximal-length sequence (M-sequence) code which is popularly used for spectral amplitude coding in OCDMA network. Hence, the proposed scheme is suitab...

Optical CDMA with Embedded Spectral-Polarization Coding over Double Balanced Differential-Detector

A spectral-polarization coding (SPC) optical code-division multipleaccess (OCDMA) configuration structured over arrayed-waveguide grating (AWG) router is proposed. The polarization-division double balanced detector is adopted to execute difference detection and enhances system performance. The signal-to-noise ratio (SNR) is derived by taking the effect of PIIN into account. The result indicates...

Performance optimization and light-beam-deviation analysis of the parallel-slab division-of-amplitude photopolarimeter.

A division-of-amplitude photopolarimeter that uses a parallel-slab multiple-reflection beam splitter was described recently [Opt. Lett. 21, 1709 (1996)]. We provide a general analysis and an optimization of a specific design that uses a fused-silica slab that is uniformly coated with a transparent thin film of ZnS on the front surface and with an opaque Ag or Au reflecting layer on the back. Mu...

Optimal beam splitters for the division-of-amplitude photopolarimeter.

Optimal optical parameters of the beam splitter that is used in the division-of-amplitude photopolarimeter are determined. These are (1) 50%-50% split ratio of the all-dielectric beam splitter, (2) differential phase shifts in reflection and transmission delta(r) and delta(t) that differ by +/- pi/2, and (3) ellipsometric parameters (psi(r), psi(t)) = (27.368 degrees, 62.632 degrees) or (62.632...
