Abstract

We propose an optical WDMA/CDMA hybrid high bandwidth local area network using coherent homodyne detection. Local injection locking to centralized highly stable sources is used for frequency selection and coherent detection. Splitting losses in a fully connect optical local area network are significant for large systems (~1000 subscribers) necessitating the use of optical amplifiers. We examine several network configurations to optimize capacity while avoiding amplifier saturation and keeping the number of amplifiers required to a minimum
