Parabolic dielectric reflector for extreme on-chip spot-size conversion with broad bandwidth
Laureano Moreno-Pozas, Miguel Barona-Ruiz, Robert Halir +5
Spot-size converters are key for efficient coupling of light between waveguides of different sizes. While adiabatic tapers are well suited for small size differences, they become i…
Ultra-compact broadband spot size converter using metamaterial cell-based inverse design
Alejandro Sánchez-Sánchez, Carlos Pérez-Armenta, José Manuel Luque-González +4
With the expansion of silicon photonics from datacom applications into emerging fields like optical I/O, quantum and programmable photonics there is an increasing demand for device…
Optimized waveguides for mid-infrared lab-on-chip systems: A rigorous design approach
Antonia Torres-Cubillo, Andrea Teuber, Robert Halir +1
Mid-infrared absorption spectroscopy is a well-established technique for non-destructive quantitative molecular analysis. Waveguide-integrated sensors provide a particularly compac…
Simultaneous measurement of refraction and absorption with an integrated near-infrared Mach-Zehnder interferometer
Antonia Torres-Cubillo, Alejandro Sánchez-Postigo, Jana Jágerská +2
Most integrated evanescent-field photonic sensors measure changes in either the real part or the imaginary part of the complex refractive index of the sample, i.e., refraction or a…
Suspended silicon waveguides for long-wave infrared wavelengths
J. Soler Penadés, A. Sánchez-Postigo, M. Nedeljkovic +12
In this paper we report suspended silicon waveguides operating at a wavelength of 7.67 mm with a propagation loss of 3.1 ? 0.3 dB/cm. To our knowledge this is the first demonstrati…
Ultra broadband waveveguide coupler using an anisotropic sub-wavelength metamaterial
Robert Halir, Pavel Cheben, Jose Manuel Luque-González +7
Multimode interference couplers are a fundamental building block in many integrated photonic systems, ranging from high-speed coherent receivers to quantum splitters. However, thei…
