    Abstract : Radio-frequency microelectromechanical systems (RF~MEMS) are highly miniaturized devices intended to switch, modulate, filter or tune electrical signals from DC to microwave frequencies. The micromachining techniques used to fabricate these components are based on the standard clean-room manufacturing processes for high-volume integrated semiconductor circuits. READ MORE

  6. 4. 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
