Integrated optics are increasingly allowing larger and more complex optical systems to be implemented at large scale and low cost. While traditionally driven by the need for compact and low-cost modules for optical Telecom and Datacom applications, these integrated systems have the potential to revolutionize the way humans interface our analog world with the digital network in which we increasingly live.
In the first part of this talk I will discuss some of the recent work performed at Bell Labs on III-V/Silicon Photonic hybrid lasers and transceivers including a 95nm tunable laser with 13dBm output power and transmitters with data rates exceeding 80Gb/s. I will then discuss how these technologies can be used for on-chip optical sensing systems, specifically for LIDAR and optical coherence tomography (OCT). I will present my work towards realizing a fully integrated OCT system as well as adding chemical specificity to this traditionally gray-scale imaging technique. Such a system will enable low-cost and chemically specific health and environmental monitoring that could fundamentally change how we sense our physical world.
