Slow light on a printed circuit board

Opt Lett. 2011 May 15;36(10):1788-90. doi: 10.1364/OL.36.001788.

Abstract

Slow-light effects induced by stimulated Raman scattering in polymer waveguides on a printed circuit board are shown to enable a widely tunable delay of broadband optical signals, suggesting an advantageous platform for optical information processing and ultrafast optical waveform transformation.
