We propose a bi-layer 5-tip edge coupler in a multilayer silicon nitride-on-silicon (SiN-on-Si) waveguide platform. The coupler is used for the integration between a monolithic 1550 nm laser and a single-mode SiN waveguide. The simulated coupling eff

Inthis paper, we report a ghost imaging (GI) method using a periodic pseudo-thermal optical field generated by a 4 × 4 silicon optical phased array (OPA) with an independently tuned grating coupler antenna. The OPA-emitted far field obtained by appl

We experimentally demonstrate an integrated strictly non-blocking silicon 4 × 4 optical switch chip that can be operated in both thermo-optic (TO) and electro-optic (EO) switching modes. It is based on the double-layer network (DLN) architecture and

A method for the dense integration of one-dimensional (1-D) photonic crystal nanobeam cavity (PCNC) based integrated sensor array (1-D-PCNC-ISA) is proposed. The 1-D-PCNC-ISA consists of multiple parallel-connected sensing channels with airgap separa

Numerical optimization was performed via COMSOL multiphysics to maximize the polarization contrast of superconducting nanowire single photon detectors (SNSPDs). SNSPDs were integrated with four different types of 1D periodic plasmonic structures capa

We propose a broadband plasmonic logic source, which is a nanostructure composed of two parallel plasmonic gap waveguides coupled with dual square ring resonators aligned in a vertical or horizontal manner. The numerical simulations show that this co

We present an all-optical switch based on photothermal effects in a silicon Mach-Zehnder interferometer (MZI) integrated with a light absorber. The metal-insulator-metal light absorber located near the longer arm of the asymmetric MZI efficiently con

We theoretically and experimentally study the dynamics of self-heating in microring resonators. We present a coupled thermal and optical model based on a lumped capacitance thermal model and optical time-domain coupled-mode theory, and verify it usin
