Phys. Rev. A 77, 053816 (2008) [4 pages]Observation of simultaneous fast and slow lightReceived 3 February 2008; published 19 May 2008 We present a microresonator-based system capable of simultaneously producing time-advanced and time-delayed pulses. The effect is based on the combination of a sharp spectral feature with two orthogonally-polarized propagating waveguide modes. We include an experimental proof-of-concept implementation using a silica microsphere coupled to a tapered optical fiber and use a time-domain picture to interpret the observed delays. We also discuss potential applications for future all-optical networks. © 2008 The American Physical Society URL:
