Demonstration of Time- and Wavelength-Division Multiplexed Passive Optical Network Based on VCSEL Array

摘要

We demonstrate a time- and wavelength-division multiplexed passive optical network system employing a vertical-cavity surface-emitting laser array-based optical line terminal transceiver and a tunable bidirectional optical subassembly-based optical network terminal transceiver. A packet error-free operation is achieved after a 40 km single-mode fiber bidirectional transmission. We also discuss an arrayed waveguide grating, a photo detector array based on complementary metal-oxide semiconductor photonics technologies, and low-cost key devices for deployment in access networks.
