Impact of feature-size dependent etching on the optical properties of photonic crystal devices

Romuald Houdré, Rolando Ferrini

Feature size dependence in Ar/Cl2 chemically assisted ion beam etching of InP-based photonic crystals (PhCs) and its influence on the optical properties of PhC devices operating in the band gap are investigated. The analysis of the measured quality factors ...

Nanophotonic crystals with chiral elements by a hot embossing process in SU-8

Shenqi Xie, Yi-Chiang Sun

We report a novel nanoprocess to fabricate 2D metallic and non-metallic nanophotonic crystals on SU-8 using hot embossing combining with a UV-curing process. The fabricated photonic crystals were characterized by optical diffraction experiments. Theoretica ...

Nonlinear optical tuning of photonic crystal microcavities by near-field probe

Laurent Balet, Massimo Gurioli

We report on a nonlinear way to control and tune the dielectric environment of photonic crystal microcavities exploiting the local heating induced by near-field laser excitation at different excitation powers. The temperature gradient due to the optical ab ...

Translation of Gbps Phase-Modulated Optical Signal From Near-Infrared to Visible Band

Camille Sophie Brès, Rui Jiang

Phase-coded optical signal was spectrally translated from the conventional near-infrared communication band to the visible band. Spectrally narrow 780-nm pump was combined with phase-modulated 1575-nm signal in a small core photonic crystal fiber (PCF), to ...

105-ns Continuously Tunable Delay of 10-Gb/s Optical Signal

Camille Sophie Brès

A continuously tunable optical delay line providing over 105 ns of 10-Gb/s optical channel is reported using a two-pump parametric process in a nonlinear optical fiber. Performance limits are measured and compared with recently reported all-optical delay r ...

Distributed fiber sensing using Brillouin echoes

Luc Thévenaz, Stella Foaleng Mafang

A simple physical description of the nonlinear optical interaction based on Brillouin echoes is presented. This technique makes potentially possible distributed Brillouin sensing down to centimeter spatial resolution while preserving the narrowband feature ...

Techniques for fully integrated intra-/inter-chip optical communication

Edoardo Charbon, Claudio Favi

In this paper we propose to replace all data and control pads generally present in conventional chips with a new type of ultra-compact, low-power optical interconnect implemented almost entirely in CMOS. The proposed scheme enables optical through-chip bus ...

Analysis of brillouin-based distributed fiber sensors using optical pulse coding

We propose the use of pulse Simplex-coding in distributed temperature sensors based on spontaneous Brillouin scattering. The analysis shows achieved performance improvement and the effect on stimulated Brillouin threshold, resulting in lower required input ...

Ultralow-dissipation optomechanical resonators on a chip

Tobias Kippenberg, Albert Schliesser

Cavity-enhanced radiation-pressure coupling of optical and mechanical degrees of freedom gives rise to a range of optomechanical phenomena, in particular providing a route to the quantum regime of mesoscopic mechanical oscillators. A prime challenge in cav ...
