Wavelength division multiplexing (WDM) is a core technology for high-bandwidth data transport system. As one of the major components in WDM system, a smaller footprint of multiplexer with two or more wavelengths is needed and photonic crystal (PhC) is a good candidate to make this approach feasible. PhC offers nanometer scale devices that can be fabricated via the existing matured silicon technology. We have modelled and simulated the design with FDTD solutions and show that multiple number of wavelengths can be generated via one-dimensional (1D) multiple cavity PhC wire. In this report, we show that with the introduction of three cavities in between embedded PhC holes, three fundamental resonance wavelengths at 1645.60, 1670.76 and 1698.68 nm were excited respectively. The number of resonance wavelengths were excited additively with the number of cavities. We observed asymmetrical free spectral ranges (FSR)s at 25.16 and 27.92 nm respectively for the generated wavelengths. The wavelengths can be tailored to any wavelength ranges; limited to silicon’s light absorption and index. However, a complex mathematical algorithm is needed to control the FSR. The results in this study will contribute to the device development for future WDM equipment miniaturization.
