2. 11. Investigation of New Concepts and Solutions for Silicon Nanophotonics

   Author : Zhechao Wang; Lech Wosinski; Kresten Yvind; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Planar integrated circuit; silicon photonics; slot waveguide; finite-difference time-domain; waveguide grating coupler; ring resonator; polarization diversity scheme; polarization beam splitter; polarization rotator; hybrid silicon laser; epitaxial lateral overgrowth; chemical-mechanical polishing.; Optics; Optik;

   Abstract : Nowadays, silicon photonics is a widely studied research topic. Its high-index-contrast and compatibility with the complementary metal-oxide-semiconductor technology make it a promising platform for low cost high density integration. READ MORE

4. 12. Vertical-Cavity Surface-Emitting Lasers: Large Signal Dynamics and Silicon Photonics Integration

   Author : Emanuel Haglund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; vertical-cavity surface-emitting laser VCSEL .; silicon photonics; high-speed modulation; semiconductor lasers; optical interconnects; laser dynamics; large signal modulation; Heterogeneous integration;

   Abstract : The GaAs-based vertical-cavity surface-emitting laser (VCSEL) is the standard light source in today's optical interconnects, due to its energy efficiency, low cost, and high speed already at low drive currents. The latest commercial VCSELs operate at data rates of up to 28 Gb/s, but it is expected that higher speeds will be required in the near future. READ MORE

5. 13. Integrated Photonics for Quantum Optics

   Author : Samuel Gyger; Val Zwiller; Stephan Steinhauer; Ali W. Elshaari; Marijn A. M. Versteegh; Matthew D. Shaw; KTH; []
