The evolution of silicon optical modulators is recalled, from the first effect demonstrations to
the characterization of high-performance devices integrated in optical waveguides. Among …

The quest for enhanced light‐matter interactions has enabled a tremendous increase in the
performance of photonic‐crystal nanoresonators in the past decade. State‐of‐the‐art …

We report designs for a silicon-on-insulator (SOI) one-dimensional (1D) photonic crystal
(PhC) nanocavity with modulated mode-gap barriers based on the lowest dielectric band …

The overall decay rate of the mode in an optical microcavity formed by a defect surrounded
by two Bragg mirrors in a monomode waveguide is driven by two mechanisms, the desired …

We experimentally demonstrate an ultra high Q/V nanocavity on SOI substrate. The design is
based on modal adaptation within the cavity and allows to measure a quality factor of 58.000 …

We identify two physical mechanisms which drastically increase the Q/V factor of photonic
crystal microcavities. Both mechanisms rely on a fine tuning the geometry of the holes …

We demonstrate in-plane microfabricated Fabry-Perot cavities with cryogenically etched
silicon/air distributed Bragg reflector (DBR) mirrors and integrated silicon-on-insulator rib …

A theoretical study of photonic bands for one-dimensional (1D) lattices embedded in planar
waveguides with strong refractive index contrast is presented. The approach relies on …

Optical microcavities are key elements in many photonic devices, and those based on
distributed Bragg reflectors (DBRs) enhance dramatically the end reflectivity, allowing for …

We present the design, fabrication, and characterization of a microcavity that exhibits
simultaneously high transmission and large resonance quality-factor (Q-factor). This …
