TL;DR: A compact electro-optic modulator on silicon-on-insulator is presented and the power of the transmitted light at the resonant wavelength is modulated by modulating the loss of the active layer included in the cavity through carrier injection.
Abstract: A compact electro-optic modulator on silicon-on-insulator is presented. The structure consists of a III-V microdisk cavity heterogeneously integrated on a silicon-on-insulator wire waveguide. By modulating the loss of the active layer included in the cavity through carrier injection, the power of the transmitted light at the resonant wavelength is modulated; ~10 dB extinction ratio and 2.73 Gbps dynamic operation are demonstrated without using any special driving techniques.

TL;DR: In this paper, an all-optical switching operation using the Kerr effect in a silica toroid microcavity was demonstrated, with an input power of 2 mW. This value is the smallest among all previously reported on-chip optical Kerr switches.
Abstract: We demonstrate experimentally an all-optical switching operation using the Kerr effect in a silica toroid microcavity. Thanks to the small mode volume and high quality factor of the silica toroid microcavity, we achieved on-chip optical Kerr switching with an input power of 2 mW. This value is the smallest among all previously reported on-chip optical Kerr switches. We also show that this value can be reduced to a few tens of μW by employing a mode with a Q factor of > 2 × 10⁷.

TL;DR: In this article, a ring-spiral coupled microcavity laser was fabricated and the ring resonator works as an oscillator and has a diameter that is slightly less than that of the spiral cavity.
Abstract: A ring-spiral coupled microcavity laser was fabricated. The ring resonator works as an oscillator and has a diameter that is slightly less than that of the spiral cavity. The spiral provides wavelength selective feedback and emits light out from the notch. As a result, the coupled cavity generates unidirectional single-frequency laser emission. Its lasing threshold is also significantly lower than a single spiral-shaped microcavity laser.

TL;DR: The direct, room-temperature, near-field mapping and spectroscopy of the optical modes of a photonic-crystal microcavity containing quantum wells are reported and the strong spatial and spectral dependence of the coupling between the sources and the microc Cavity is demonstrated.
