N2 - We report the first (to our knowledge) demonstration of photonic chip based tunable slow and fast light via stimulated Brillouin scattering. Slow, fast, and negative group velocities were observed in a 7 cm long chalcogenide (As 2S3) rib waveguide with a group index change ranging from ∼ ? 44 to +130, which results in a maximum delay of ∼23 ns at a relatively low gain of ∼23 dB. Demonstration of large tunable delays in a chip scale device opens up applications such as frequency sensing and true-time delay for a phased array antenna, where integration and delays ∼10 ns are highly desirable.
