Development and Applications of On-chip Integrated Lasers and Waveguide Amplifiers
There is a growing demand for optical amplifiers capable of amplifying high rate signals and for on-chip micro-lasers with tunable output wavelengths. Specific areas of application of such devices include trace-gas detection, lab-on-a-chip, optical-coherent communications, optical beam-forming, and board level optical interconnects. In the first part of the talk we will review our latest results on development of rare-earth ion doped waveguide amplifiers for use in optical backplanes envisaged to replace the currently existing electronic printed circuit technology. We will discuss integration approaches of such technology with silicon photonics and optical backplanes. We will also report on utilization and optimization of the focused-ion-beam (FIB) technique for the fabrication of nanostructures and microcavities on optical waveguides for realization of integrated photonic devices. In particular, we will report the first on-chip waveguide laser in solid state double tungstates and realization of ring micro-laser devices compatible with silicon photonics.
