Abstract
A silicon-on-insulator microring with three superimposed gratings is proposed and characterized as a device enabling 3 Ã 3 optical switching based on orbital angular momentum and wavelength as switching domains. Measurements show penalties with respect to the back-to-back of <1 dB at a bit error rate of 10â9for OOK traffic up to 20 Gbaud. Different switch configuration cases are implemented, with measured power penalty variations of less than 0.5 dB at bit error rates of 10â9. An analysis is also carried out to highlight the dependence of the number of switch ports on the design parameters of the multigrating microring.File in questo prodotto:
