Transmission and group delay characteristics of a single-quantum-dot-(QD)-embedded double-cavity array and a triple-cavity array are compared theoretically in the weak coupling regime. When the extrinsic cavity decay rate is comparably higher than the intrinsic cavity decay rate at equal coupling strengths and normalized detuning values, transmission values of both systems converge with each other but the phase delay generated at triple-cavity systems is higher than that of the single-QD-embedded double-cavity array system. The results confirmed by the transmission calculations for both cases provide a comparative tool for designing on chip wavelength division multiplexing systems.
