Compact photonic gateway for dynamic path control using acousto-optic tunable filter

A compact photonic gateway for wavelength-path control with a simple configuration at low cost was developed. The gateway achieves wavelength-path control by using acousto-optic tunable filters (AOTF). The fabricated four-channel integrated AOTF device exhibits a high performance with regard to polarization-independent characteristics, side-lobe suppression, higher extinction ratio, and narrower bandwidth for 100 GHz spacing. An AOTF subsystem was fabricated by combining an AOTF with the control circuit to exploit the AOTF's high-speed switching to the full and operate it stably for practical use and achieve stable operation of the AOTF. We manufactured the photonic gateway node by assembling the AOTF subsystem with the provisioning control and redundant system.
