Slow-light regime and critical coupling in highly multimode corrugated waveguides

Slow-light regime and critical coupling in highly multimode corrugated waveguides

Slow Light in Optical Waveguides

As evidenced by this Volume, there has been a flurry of activity over the last decade on tailoring the dispersive properties of optical materials [1]. What has captured the attention of the research community were some of the early results on creating spectral regions of large normal dispersion [2–4]. Large normal dispersion results in extremely small group velocities, where the group velocity ...

Loss engineered slow light waveguides.

Slow light devices such as photonic crystal waveguides (PhCW) and coupled resonator optical waveguides (CROW) have much promise for optical signal processing applications and a number of successful demonstrations underpinning this promise have already been made. Most of these applications are limited by propagation losses, especially for higher group indices. These losses are caused by technolo...

Dark modes, slow modes, and coupling in multimode systems

We present general aspects of coupling among two or more families of modes with a view to deepen the insight on so-called “dark modes.” We first review the relationship of dark modes, “coherent population trapping,” “rotating wave approximation,” “coupled-mode theory,” and a few related concepts. The approach we emphasize is related either to inhomogeneous light–matter strong coupling or to the...
