Large-Port-Count MEMS Silicon Photonics Switches

Niels Quack

Highly integrated optical circuit switch (OCS) with large port counts (~100x100) is achievable by combining silicon photonics and MEMS technologies. We will review the design trade-offs, performance scaling, and the current state of the art. ...

Manipulating Bloch surface waves in 2D: a platform concept-based flat lens

Hans Peter Herzig, Elsie Barakat, Libo Yu, Tristan Sfez, Lubos Hvozdara, Joab Di Francesco

At the end of the 1970s, it was confirmed that dielectric multilayers can sustain Bloch surface waves (BSWs). However, BSWs were not widely studied until more recently. Taking advantage of their high-quality factor, sensing applications have focused on BSW ...

High-Q silicon photonic crystal cavity for enhanced optical nonlinearities

Romuald Houdré, Vincenzo Savona, Momchil Minkov, Ulagalandha Perumal Dharanipathy, Mario Lucien Henri Tonin

We fabricate and experimentally characterize an H0 photonic crystal slab nanocavity with a design optimized for maximal quality factor, Q = 1.7 x 10(6). The cavity, fabricated from a silicon slab, has a resonant mode at lambda = 1.59 mu m and a measured Q- ...

Bloch Surface Based Platform for Optical Integration

Hans Peter Herzig, Elsie Barakat, Richa Dubey

A novel dielectric multilayer platform sustaining Bloch surface waves is investigated for integrated photonic chips. These surface waves can be manipulated by two dimensional dielectric optical components patterned on top of the platform. We study the prop ...

Optimal antibunching in passive photonic devices based on coupled nonlinear resonators

Vincenzo Savona

We propose the use of weakly nonlinear passive materials for prospective applications in integrated quantum photonics. It is shown that strong enhancement of native optical nonlinearities by electromagnetic field confinement in photonic crystal resonators ...

Near-field imaging

Libo Yu

Bloch surface waves (BSWs) are surface electromagnetic waves excited at the interface between a truncated periodic dielectric multilayer and a surrounding medium. This particular solution to the Maxwell equations in stratified media has been known since th ...

Method and arrangement for measuring the distance to an object

Cristiano Niclass

Arrangement (10) for measuring the distance to an object, comprising: a photonic source for illuminating said object using a continuous modulated photonic wave, a solid-state image sensor, comprising an array of avalanche photodiodes and a plurality of cir ...

Subwavelength Metallic Structures for Sensing

Qing Tan

Following rapid developments in biotechnology and medicine, optical sensing promises to be extremely important in various applications such as drug discovery, environmental monitoring, etc. Refractive index (RI) based optical sensing is straightforward to ...

Uncoupled photonic band gaps

We theoretically investigated the symmetry properties of the modes in two-dimensional square lattice photonic crystals in order to study phenomena that would enable new frontiers in the applications of photonic crystals. Using group theory, symmetry analys ...

Ideal homoatomic and heteroatomic photonic crystal molecules

Laurent Balet, Massimo Gurioli

A local tuning of the modes of photonic crystal systems both to blue and to red sides of the resonance is implemented by nano-infiltration/evaporation of water and laser micro-oxidation. This technology is used to completely control coupled photonic nanoca ...
