The longitudinal mode-field components in strongly confining crystalline-silicon waveguides cause a forward–backward asymmetry of the stimulated Raman effect. This nonreciprocity can be used to realise isolators with dynamically reconfigurable isolation direction.

Inspec keywords: silicon; amplification; optical waveguides
