Abstract

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 (As2S3) rib waveguide with a group index change ranging from 44 to +130, which results in a maximum delay of 23ns at a relatively low gain of 23dB. 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 10ns are highly desirable.

Calculated (solid curves) and measured (circles) group index profile for (a) slow light and (b) fast light. A sinusoidal modulation of 10 MHz for slow light and 3 MHz for fast light was imposed on the probe carrier wave, whose frequency was detuned from the Stokes (anti-Stokes) for slow (fast) light. The coupled CW pump powers of 152mW for slow light and 91mW for fast light were used.
