Abstract
We propose a novel superstructured fiber Bragg grating (SSFBG) based single-input multiple-output (SIMO) en/decoder, which can simultaneously process a group of independent optical codes with a specific permutation and combination of code patterns and spatially separate encoded and decoded signals into different optical paths. The number of optical codes processed by the SIMO en/decoder can be flexibly changed. We theoretically and experimentally investigate the coding performance of the SIMO en/decoder and discuss the unique features of the proposed device. In the experiment, we employ the SIMO en/decoder for optical label processing in an optical-code based optical packet switching system with the data rate of 10 Gbit/s and the packet rate of 312.5 MHz. The four- SSFBG based SIMO en/decoder are capable of simultaneously generating/recognizing four 31-chip 640 Gchip/s optical code based labels and distribute the labels into four designated destinations.
