    Abstract

    Integrated optics is a rapidly advancing research field, enabling the miniaturization of a variety of optical functions and their implementation on a single chip. We discuss several technologies and devices for the realization of on-chip amplifiers, lasers and optical sensors. Recent research results comprise high-speed (170 GBit/s) amplifiers and narrow-linewidth (1.7 kHz) laser sources, both heterogeneously integrated onto silicon substrates, as well as the worldwide first continuous-wave solid polymer laser and highly efficient on-chip lasers for operation at the 1- and 2-■m wavelength range. On the sensor side we highlight recent results based on mechano-optic actuation, optofluidics and on-chip spectrometry for applications in such diverse fields as gas sensing, DNA detection, Raman spectroscopy and optical coherence tomography.
