Abstract

We propose and characterize nanowire-embedding in photonic crystal. This embedding method becomes a novel fabrication process for photonic crystal line defect, which enhances freedom in waveguide manufacturing. The characteristics of the nanowire defect waveguide are investigated by using a cascaded low pass filter model in circuit theory. We can find that the wave propagation characteristics correspond to the specific case of optical branch phonon vibration in solid crystals, where diatomic vibration occurs with multiple particle interaction. Actually, the dispersion characteristics of the proposed system are similar to the optical branch phonon vibration of the transition metal compounds. There are multiple modes (i.e., different Bloch wave numbers) for an optical frequency with local minimum of frequency at the lower wave number. Waveguide bending ability was confirmed by using FDTD (finite difference time domain) simulations. Nanowire-embedding in photonic crystal is expected to open a new territory to the field of photonic integrated circuit from fabrication process to waveguide and various photonic devices.
