High SFDR ‘Super-Ring’ microresonator based True-Time-Delay (TTD)

摘要

This paper described the first results demonstrating the Super-Ring tuning concept applied to a 40 microresonator based TTD device, operating with the Balanced SCISSOR scheme. Tunable delay up to 515ps of a 20GHz BW RF photonic signal was shown, using only two drive voltages, with SFDR over 110dB.Hz for delays up to 300ps.
