Low limit of detection silicon photonic sensor with extremely-low-cost laser source
(2020-10-06)Integrated photonic biosensors have demonstrated low bulk detection limits down to 1e−7 refractive index units. Nevertheless, most rely on expensive optical sources, such as DFB lasers. Here, we experimentally demonstrate ... -
Low-cost step aerobics system with virtual aerobics trainer
(2014-06-30)In this paper a low-cost step-aerobics instructor simulation system is presented. The proposed system analyses a given song to iden- tify its rhythmic pattern. Subsequently, this rhythmic pattern is used in order to ... -
Low-loss curved waveguide grating wavelength demultiplexer
(2021)We demonstrate a compact wavelength demultiplexer for the silicon on insulator platform based on the curved waveguide grating (CWG) architecture. We mitigate off-chip radiation loss by enforcing the single beam condition ... -
Measuring odd- and even-mode propagation constants of coupled-lines by means of the lattice network
(2019-10-30)A classic method for measuring the propagation constant of transmission lines is the one proposed by Bianco and Parodi more than four decades ago [1]. It is based on the invariance of the cross ratio of four complex numbers ... -
