A century after the first optical cavity, coupled resonator optical waveguides (CROWs) were
conceived as a new way to guide light on a photonic chip. Controlling chains of coupled …

The next generations of wireless communications are promising high capacity, low latency,
and high throughput, enabled by millimeter wave spectrum. Beamforming and beam …

As light cannot be stopped or directly stored in any media, optical delay lines are usually
used to temporally trap the optical signals. We report a wide-range continuously tunable …

Phased array radars have remarkable advantages over radars with single-element antenna
in terms of agility, flexibility, robustness, and reconfigurability. Current pure-electronic …

In this paper, we report a direct comparison between coupled resonator optical waveguides
(CROWs) and photonic crystal waveguides (PhCWs), which have both been exploited as …

We demonstrate a distortion free tunable optical delay as long as 135 ps with a 10 GHz
bandwidth using thermally tuned silicon microring resonators in the novel balanced …

We report, for the first time, an integrated photonic signal processor consisting of a
reconfigurable optical delay line (ODL) with a separate carrier tuning (SCT) unit and an …

Optical delay lines (ODLs) are one of the key enabling components in photonic integrated
circuits and systems. They are widely used in time-division multiplexing, optical signal …

Three optical ring resonator (ORR)-based integrated ultra-low-loss silicon nitride 1× 4
optical beamforming networks (OBFNs) for millimeter-wave (mmW) beamsteering are …

Tunable optical delay lines are one of the key building blocks in optical communication and
microwave systems. In this work, tunable optical delay lines based on integrated grating …
