TL;DR: In this article, the authors compared the performances of optical millimeter-wave generation or up-conversion using external modulators based on different modulation schemes and found that the OCS modulation scheme has the highest receiver sensitivity, highest spectral efficiency and smallest power penalty over long-distance delivery.

TL;DR: Transmission characteristics of two coupled identical cavities, of either standing-wave (SW) or traveling- wave (TW) type, are analyzed, based on temporal coupled mode theory, and it is interesting to notice that a side-coupled SW cavity system performs similarly to an under-couple TW cavity.

TL;DR: The microring resonator operates near the critical coupling region, and can take the first order derivative of the optical field, and features compact size thus is suitable for integration with silicon-on-insulator (SOI) based optical and electronic devices.

TL;DR: A compact silicon polarization beam splitter based on grating-assisted contradirectional couplers (GACCs) that exhibits tolerance in width variation, and the polarization extinction ratios remain higher than 20 dB for both polarizations when the width variation is adjusted from + 10 to -10 nm.

TL;DR: In this article, a broadband photonic radio frequency (RF) phase shifter based on a silicon microring resonator was proposed and demonstrated for a 40 GHz signal with a 0-4.6-rad tuning range.
