| Abstract | We demonstrate binary spectral phase coded waveform discrimination at 10 GHz for narrow band optical code-division multiple-access (NB-OCDMA) via direct electrical detection without using any optical hard-limiter. Only 9 phase-locked, 10 GHz spaced, spectral lines within a 100 GHz spectral window are used for the phase coding. Considerably high contrast ratio of 5 between signal and multiuser access interference noise can be achieved for <TEX>\$4\{\{\textblackslash\}times\}10\{\textblackslash\};G\{\textblackslash\};pulse/sec\$</TEX> timing coordinated OCDMA at a simple electrical receiver with 50 GHz bandwidth. |
