Fiber Bragg grating (FBG) optical reflectors have become used for encoding and decoding optical code division multiple assess (OCDMA) data. We observed that only about 20% of the power that enters into an optical FBG en/decoder is reflected and the remaining 80% is not used in the en/decoding process. We present a novel architecture that will enable both cost and energy efficiency in the process of generating optical CDMA codes. The architecture achieves effective utilization of available optical power. We have been able to achieve power savings of up to 3dB for a 4-user OCDMA system.
