We present our recent work on the realization of III-V-on-silicon mode-locked lasers and integrated nonlinear waveguides for the realization of integrated frequency combs. OCIS codes: (320.6629) Supercontinuum generation; (190.4390) Nonlinear optics, integrated optics

We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication. Visible and infrared multi-aperture interferometry requires many optical functions (spatial filtering, beam combination, photometric calibration, polarization control) to detect astronomical signals at very high angular resolution. Since ...

Three-dimensional direct-write lithography into diffusion-mediated photopolymers developed for holography is shown to create 10 micron single-mode waveguides. We demonstrate low-loss waveguides, 90 degree bends off of encapsulated mirrors and fabrication of waveguides to embedded fibers. ©2007 Optical Society of America OCIS codes: (160.5470) Polymers, (160.2900) Holographic recording materials...

Recent progress in the field of integrated optics in Japanis reviewed. The research effort on planar guides, active integratedoptics, and microoptics is outlined and pertinent references aregiven.
