Shottky–type Al0.6Ga0.4N solar-blind avalanche photodiodes have been fabricated and characterized under front and back illuminated conditions. The photodiodes exhibited dark currents below 1pA in the measuring range. Photocurrent under front illumination was lower than photocurrent under back illumination in the reverse-bias region below 35 V, but then exceeded the latter as the reverse bias became larger. Impact ionization coefficient for electrons is larger than that for holes as derived from the gain-voltage curves under the front and back illuminations.

We propose a multi-level phase-change memory device based on a Ge2Sb2Te5 (GST)-filled silicon slot nanobeam cavity. Simulations show that the nanobeam resonance can be tuned step-by-step through phase change of the GST, allowing for multi-level storage of optical data.

Anti-symmetric multimode periodic waveguide cavities (AM-PWCs) are proposed and demonstrated in this paper. Due to transverse symmetry-breaking of the anti-symmetric multimode periodic waveguide, anti-crossing of the fundamental mode and 1st-order mode is realized. Reflection-free cavity filters based on this characteristic are demonstrated. Experimental results on silicon-on-insulator platform shows that broadband (> 100 nm) reflection suppression (< −15 dB) and high-Q (1.8 × 104) AM-PWCs can be achieved using existed design methodology and fabrication facility.
