Deskripsi
Twisted light in the form of orbital angular momentum (OAM) can provide an additional spatial dimension for information transmission. Here, the authors demonstrate a prescription for OAM generation using photonic crystal ring resonators, in which high cavity quality factors (up to 106) are retained.
