Magneto-optical non-reciprocal devices in silicon photonics
Science and Technology of Advanced Materials, 2014 Silicon waveguide optical non-reciprocal devices based on the magneto-optical effect are reviewed. The non-reciprocal phase shift caused by the first-order magneto-optical effect is effective in realizing optical non-reciprocal devices in silicon ...

Polarization-Independent Mode-Evolution-Based Coupler for the Silicon-on-Insulator Platform
IEEE Photonics Journal, 2018 We demonstrate a polarization-independent mode-evolution-based coupler for the silicon-on-insulator platform. The measured coupler has negligible insertion loss over a bandwidth of about 100 nm, i.e., from 1500 to 1600 nm.

Exploring the Potential of Microwave Annealing for Enhancing Si‐based GeSn Lasers
Advanced Materials Technologies, EarlyView.We explore low‐thermal‐budget microwave annealing to enhance the performance of group‐IV GeSn lasers on Si. Microwave annealing under optimal conditions can simultaneously relax unwanted compressive strain and enhance the material quality of the GeSn active layer, thereby reducing the threshold and increasing the laser operating temperature.

Design and Fabrication of Broadband Polymer Mode (De)Multiplexer Using a Direct Inscribing Method
IEEE Photonics Journal, 2018 We demonstrate the design and fabrication of a mode (de)multiplexer based on the tapered mode-selective coupler. The proposed device is directly inscribed in the substrate material by a needle-type liquid micro-dispenser and a three-axis robot stage ...

Coupling terahertz wave into a plasmonic waveguide by using two ribbon waveguides
Results in Physics, 2020 We proposed the design of coupling terahertz wave into a plasmonic waveguide via using two alumina ribbon waveguides. The dispersion relation of fundamental alumina waveguide mode shows that it has intersections with plasmonic modes, resulting in the ...

Clearing a path for light through non-Hermitian media
NanophotonicsThe performance of all active photonic devices today is greatly limited by loss. Here, we show that one can engineer a low loss path in a metal-clad lossy multi-mode waveguide while simultaneously achieving high-performance active photonic devices.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
