Abstract

Unidirectional waveguides and slow light waveguides both play the key roles in the modern communication system. The unidirectional waveguides do not support slow light. The traditional slow light waveguides are always limited to the group velocity dispersion. To combine both the functionalities of unidirectional transmission and slow light into one waveguide, we add a surface defect into unidirectional waveguide to modulate the odd mode dispersion. Through a structure optimizing, a dispersionless and slow unidirectional waveguide is obtained. The waveguide with compound functionalities is confirmed through the frequency-domain and time-domain simulations.
