With the flexibility in dispersion designs of these waveguides, a variety of indirect photonic transitions can be envisaged. The signal wave transmitted through the front experience an inter-band transition, while the wave reflected from the front - an intra-band transition. Theory and experimental results are presented.enTechnikConference Paper10.1364/ACPC.2017.S4D.2Other
