“…Consequently, the number of simultaneous transmission users will not increase a lot due to multiple access interference (MAI) noise. In addition, various methods of MAI cancellation schemes have been reported to eliminate crosstalk in recent years [34][35][36]. To some extent, the number of simultaneous transmission users will be furtherly enlarged through these techniques.…”

A structure of serially coupled dumbbell microring resonator (SCDMRR) is proposed based on vernier effects to obtain wider free spectral range (FSR), and a new kind of two-dimensional optical en/decoder is designed taking advantage of the SCDMRR. Numerical simulations are done to analyze reflection spectrum of the SCDMRR and test performance of the proposed en/decoder according to the coupled mode theory. In addition, the coupling coefficients of both ring-bus and ring-ring are optimized to suppress the spurious mode. Furthermore, a comparison is performed between the en/decoder based on SCDMRRs and the en/decoder using ordinarily coupled identical three-order-ring resonators (OCITRR). The results show that the FSR is 13nm for SCDMRR with the ring radius of 40um-30um-40um, which is about four to five times larger than that of OCITRR. Such FSR will contain more column numbers of parallel-coupled MRR and the code cardinality generated by the proposed device is 3.43E17. For the SCDMRR-based en/decoder, the peak to wing ratio (P/W) of auto-correlation signal and peak power ratio (P/C) between the auto-/cross-correlations are 6.39 and 8.71, which have risen by approximately 33% and 8% against that of en/decoder based on OCITRR, respectively.

“…As one of the nature of light, the phase of coherent light has been effectively used in various optical systems, where the passive interference behavior between multiple signals is easily used. Using this feature, label recognition techniques have been investigated for photonic routers based on optical code correlation [2][3][4][5][6][7][8][9] . However, most of the proposed systems could not recognize all the binary codes because only the type of codes that provide enough discrimination between auto-correlation and cross-correlation were recognized.…”

This paper discusses optical label recognition for photonic label routing. The label recognition is one of the key functions in photonic label routing related functions including optical label extraction, recognition of the label and label rewriting. In a previous study, we have proposed a basic waveguide-type circuit for the recognition of an optical label encoded in quadri-phase-shift-keying (QPSK) format, which consists of a 3-dB directional coupler, two Y-branches and an asymmetric X junction coupler. In order to increase the number of labels represented by the same symbol number, we propose 8PSK recognition circuits based on the QPSK recognition circuit. The input-output relation of the proposed circuits is theoretically discussed and the noise tolerance is also investigated. From the theoretical analysis, the proposed optical-waveguide circuits recognize the 8PSK labels by detecting the position of the output port having either the maximum or minimum intensity. The bit-error performance of the proposed circuits is clarified by computer simulation. It is found that the minimum-output detection scheme for a one-symbol 8PSK label is superior from the viewpoint of noise tolerance. The proposed method also addresses the scalability of two-symbol 8PSK coded labels. The maximum-output detection scheme demonstrates improved scalability performance.
