Abstract

A highly compact and scalable microring-laser-based optical-add multiplexer is presented for wavelength division multiplexed bus networks. The output of a 40m-radius microring laser is vertically coupled to a passive waveguide bus and the chip is subsequently mounted in a butterfly package with fibre pigtailing at both input and output. In the first such experiment with a microring-based module, a wavelength channel is added into a wavelength multiplexed fibre-optic link with negligible power penalty. Successful transmission of a 2λ×2.5Gbit/s signal over 25km is demonstrated for a 0.9nm channel spacing.
