8-channel AWG-based multiwavelength laser fabricated in a multi-project wafer run

We demonstrate one of the first monolithically integrated multiwavelength lasers fabricated in an industrial fab exploring a generic foundry model. The lasers were realized by participating in multi-project wafer run. We present 8-channel sources that use arrayed-waveguide gratings (AWGs) as intra-cavity filters, in two configurations, with and without booster amplifier. The devices operate in the third telecommunication window, around 1.55 μm. The measured optical output power is up to 5dBm with side mode suppression ratio (SMSR) better than 40 dB. Our lasers were fabricated on an indium phosphide (InP) based platform.
