TL;DR: It is shown that extending the ring cavity length increases the resonator quality factor, and thereby enhances the sensor resolution and minimum level of detection, while at the same time relaxing the tolerance on the coupling conditions to provide stable and large resonance contrast.

TL;DR: An ultra-compact comb filter using an add-drop ring resonator with an Archimedean spiral cavity that exhibits a quality factor Q > 35,000, extinction ratios > 10 dB, and an excellent power uniformity over a 40 channel wavelength span is presented.

TL;DR: In this paper, the spectral characteristics of a ring resonator made of Si photonic wires are modeled using mode expansion of supermodes of the directional coupler, and the influence of the coupling coefficient, loss factor and waveguide dispersion on the spectral features are analyzed in detail.

TL;DR: In this article, a 1 /spl times/2 waveguide digital optical switch with electrically reconfigurable output waveguide arms is proposed and demonstrated, which exhibits a 20dB switching contrast ratio.

TL;DR: In this article, a bend loss attenuator with electrically modulated bend loss is proposed, which requires less than half the current of a comparable straight waveguide attenuators to achieve 3'dB attenuation.
