  2. 1. Designs and simulations of silicon-based microphotonic devices

    Author : Daoxin Dai; Sailing He; Siegfried Janz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; waveguide; silicon-on-insulator SOI ; arrayed waveguide grating AWG ; Elektronik; Electronics; Elektronik;

    Abstract : The characteristics of a silicon-on-insulator (SOI) rib waveguide, including the bending loss of a multimode bent waveguide and the birefringence of a rib waveguide, are analyzed by using a finite-difference method (FDM). Based on a detailed analysis for a multimode bent waveguide, an appropriately designed multimode bent waveguide for reducing effectively the bending loss of the fundamental mode is realized.

    Abstract : When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. READ MORE
