Abstract
). At 1533 nm, the odd mode exhibited an impressive interaction factor of 0.836; while at 1654 nm, the even mode achieved an even higher interaction factor of 1.308, and both retain relatively low propagation losses. This research not only introduces innovative strategies for expanding slow light bandwidth, but also presents a promising avenue for on-chip multi-gas detection.
