“…The effective refractive index (n eff ) of the lowest order waveguide mode is usually more than 1.5 times smaller than n s . The reduction in n eff introduces large radiation loss in WGM and cavity Q is reduced drastically especially for sub-wavelength diameter, D [10]. The metal-capped microdisk structure has been proposed to increase n eff and therefore Q [11].…”

Metal-capped microdisk cavity supporting surface plasmon polaritons (SPP)-guided whispering gallery mode (WGM) can achieve higher cavity factor Q than traditional microdisk cavity in sub-wavelength dimensions. We have numerically analyzed the limiting factors on Q using finite difference time domain method. The Q of SPPguided WGM is primarily limited by the loss of metal. A thin metal-sandwiched microdisk cavity supporting longrange surface plasmon polariton mode was proposed to reduce the metal loss. The proposed cavities have been shown to increase cavity Q by more than 15-fold and reduce threshold gain by more than threefold as opposed to traditional microdisk cavities.

“…In order to realize high-Q ring resonators, the bend radii of the ring resonators have to be large enough to avoid the dominant bending loss. The model shows that the optical mode is better confined at shorter wavelengths and thus allows smaller bend radius without bending loss; however, the scattering loss at shorter wavelengths is higher [19]. For 5.3-μm-wide and 50-nm-thick Si 3 N 4 waveguides, the radii have to be larger than 7 mm, 3 mm, and 2 mm in 1550nm, 1310nm, and 1060nm wavelength regimes to have negligible bending loss, and their corresponding scattering-limited losses are 0.4 dB/m, 0.8 dB/m, and 2.1 dB/m.…”

Abstract:We demonstrate planar Si 3 N 4 ring resonators with ultra-high quality factors (Q) of 19 million, 28 million, and 7 million at 1060 nm, 1310 nm, and 1550 nm, respectively. By integrating the ultra-low-loss Si 3 N 4 ring resonators with laterally offset planar waveguide directional couplers, optical add-drop and notch filters are demonstrated to have ultra-narrow bandwidths of 16 MHz, 38 MHz, and 300 MHz at 1060 nm, 1310 nm, and 1550 nm, respectively. These are the highest Qs reported for ring resonators with planar directional couplers, and ultra-narrowband microwave photonic filters can be realized based on these high-Q ring resonators.

“…This has a positive effect on the scattering loss and the coupling efficiency. It can be shown that taking into account the large vertical confinement, the scattering loss, which is caused by the sidewall roughness of the microdisk, scales roughly linearly with the thickness of the device [32]. The coupling efficiency to the underlying waveguide also increases for a thinner structure, because there exists a larger exponential tail in the cladding, and thus, also a larger overlap with the silicon waveguide.…”

Abstract-We review recent progress in nanophotonic devices for compact optical interconnect networks. We focus on microdisklaser-based transmitters and discuss improved design and advanced functionality including all-optical wavelength conversion and flip-flops. Next we discuss the fabrication uniformity of the passive routing circuits and their thermal tuning. Finally, we discuss the performance of a wavelength selective detector.Index Terms-Flip-flop, heterogeneous integration, microdisk laser (MDL), network-on-chip, photonic integration, process uniformity, silicon-on-insulator (SOI), wavelength conversion.
