The integration of single-photon and photon-number-resolving detectors with single-photon sources and passive circuits is essential to realise fully-functional quantum photonic integrated circuits. We have recently demonstrated the first waveguide single photon detectors (WSPDs) [1] and a polarisation-independent on-chip autocorrelator for the measurement of the second-order correlation function g...
By employing the enhanced phase transfer of single microring resonator, the enhanced intensity sensing is obtained based on the dual microring resonator with coupled mode theory.
A low loss sharp bend is proposed and analyzed in the slow-light waveguide which is consisted of a series of silicon nanopillars. More than 90% of transmission over 100 nm bandwidth is obtained.
A Mach-Zehnder modulator based on n-p-n electronic configuration and a single mode waveguide is proposed and analysed. The excellent optical confinement together with the reversed biased operation enables high efficiency and fast modulation. An optimum overlap between the optical field and the depletion regions warrants a VpiLpi merit of 0.87 V ldr cm. The rise and fall times are 0.063 and 0.006 ns,...
Based on conventional lithography and anisotropic etching of Si, a size reduction technology is proposed to achieve low-loss nano-scale optical waveguides in silicon-on-insulator (SOI), which would find abroad applications in highly-integrated optical interconnects and integrated photonic circuits.
