Abstract
A reconfigurable optical add/drop multiplexer (R-OADM) device is proposed based on 2-D photonic crystals (2-D PCs) with a triangular lattice of air holes. It consists of channel add/drop filters, two bends with 120-deg bending angles, and a 2×2 directional coupler switch. Chirp structures are introduced in the directional coupler switch to improve its extinction ratio. At λ=1550 nm, the device is ultracompact with a net footprint 30×22 µm, excluding its external device. It is far smaller in size than other corresponding devices implemented through ring resonators. The device is numerically calculated by the finite-difference time-domain (FDTD) method, and simulation results confirm that the R-OADM device can be used for dynamically wavelength routing.
