TODO - Topologically protected transport has recently emerged as an effective
means to address a recurring problem hampering the field of slow light
for the past two decades: its keen sensitivity to disorders and
structural imperfections. With it, there has been renewed interest in
efforts to overcome the delay-time-bandwidth limitation usually
characterizing slow-light devices, on occasion thought to be a
fundamental limit. What exactly is this limit, and what does it imply?
Can it be overcome? If yes, how could topological slow light help, and
in what systems? What applications might be expected by overcoming the
limit? Our Perspective here attempts addressing these and other related
questions while pointing to important new functionalities both for
classical and quantum devices that overcoming the limit can enable.
