Abstract
Transmissions and resonant tunneling of two-dimensional (2D) photonic superlattices (PhSLs) are discussed. We consider PhSL composed of two alternating 2D-photonic crystals. The structure is denoted as A/B/A/B……A/B, where photonic crystals A and B act as photonic wells and barriers, respectively. The transmission coefficient is calculated using the Transfer Matrix Method (TMM) in combination with Bloch theorem. The transmission spectra of the PhSLs indicate that the formation of photonic miniband and minigap inside the wells. The positions and number of the minibands can be artificially tuned by varying the well width. By appropriately choosing the structure parameters, these interesting results can be used to develop new photonic devices.
