SNSPDs evanescently coupled to silicon waveguides can have low overall system efficiency (~2% [1]) due to mode mismatch with optical fibers. We propose to improve this by substituting the silicon waveguides with silic...

We report efficient fiber-to-waveguide and 3D chip-to-chip light coupling devices based on bent metal-clad waveguides. According to our FDTD simulation, the coupling efficiency is over 80% within a broad range of work...

The development of a square holey cladding dielectric waveguide for chip-to-chip THz communication is presented. Designed to operate in the range of 180-360GHz, measured and simulated mode profiles of fabricated waveg...

In this paper we investigate mode nonorthogonal properties and their effects on the sound power attenuation in a waveguide with impedance boundary conditions. By introducing two quantities: self-nonorthogonality Kp, w...

Mid-infrared waveguides of different Ge core thicknesses have been developed in Ge-on-SOI. Minimum propagation loss of ∼8 dB/cm has been achieved for 0.85 μm thick Ge core using 3.682 μm laser excitation. The waveg...

We demonstrate phase sensitive amplification based on pump-degenerate four-wave mixing in highly nonlinear low-loss waveguides. A net gain of 6 dB (including propagation losses) is achieved, with an extinction ratio o...

Thermally stable four zero-dispersion wavelengths with ultra-flat dispersion profile in highly-nonlinear Si-organic-hybrid slot-waveguides are reported. Such structures will be highly suitable for wavelength conversio...
