It's like what I stated:
A term initially popularized by Japanese fans, and then unofficially picked up by one of the members of the production team who wrote the synopsis for Zi-O's 45th episode, and then that synopsis was referenced to by the authors of KR Zukan (which, if I remember correctly, was launched during Zi-O's mid-season).

Yes, Decade's OP did use the word "aurora", but I think it was only used as a metaphor by the lyricist (Shoko Fujibayashi), not as an actual name for the interdimensional portal. Although, it might also be one of several factors that contributed to the popularization of the term "aurora curtain" by Japanese fans.
