As a consequence, the as-prepared tin-doped porous silicon microspheres embedded with tin nanoparticles show a high reversible capacity (1165.6 mA h g –1 at the 400th cycle at 1 A g –1), excellent ...

We introduce a bandwidth enhancement technique for traveling-wave Mach-Zehnder modulators (TW-MZM). This approach reduces the microwave attenuation caused by the loaded PN junction capacitance. We ...

Based on a Silicon and Lithium Niobate hybrid integration platform, we demonstrate Mach-Zehnder modulators that feature low insertion loss, low drive voltage, large modulation bandwidth, high ...
