Membrane InP saturable absorbers on silicon as building blocks for transparent optical networks Universiteit Gent
As silicon photonics continues to gain research and industrial relevance, some of the building blocks in this technology such as modulators and switches still suffer from limitation when it comes to insertion losses and/or extinction ratio. In the past two years we have been investigating a promising new building block for silicon on insulator (SOI) circuits which is based on ultra-thin narrow stripes of InP bonded on top of SOI, which operate ...
Fabrication of polymer inverse opals with linear and nonlinear optical functionalities using a sandwiching approach KU Leuven
Three-dimensionally (3D) ordered macroporous materials combine interesting structural and optical properties. Accessible and economic fabrication is essential to fully explore the unique possibilities these materials present. A common method to fabricate 3D ordered macroporous materials is by self-assembling colloids, resulting in so-called opals. A templating strategy is then often used to introduce additional functionality inside the porous ...
Tuning silicon-on-insulator integrated optical components Universiteit Gent
Silicon-on-insulator is an ideal material platform for the fabrication of integrated optical components due to the high index contrast, the compatibility with CMOS processes and the transparency for telecom wavelengths. A major drawback of silicon is the low electro-optic coefficient which inhibits the realization of modulators or switches. Liquid crystal can be used as a cladding layer and this enables to tune and modulate optical components in ...
Progress in III-V/SOT photonic integrated circuits Universiteit Gent
In this paper we review our work in the field of III-V/SOI photonic integrated components for intra-chip optical interconnect applications. III-V/SOI microdisk light sources, modulators and switches, together with resonant III-V/SOI photodetectors will be discussed.
Integrated silicon photonic MEMS Interuniversitair Micro-Electronica Centrum vzw Universiteit Gent
Silicon photonics has emerged as a mature technology that is expected to play a key role in critical emerging applications, including very high data rate optical communications, distance sensing for autonomous vehicles, photonic-accelerated computing, and quantum information processing. The success of silicon photonics has been enabled by the unique combination of performance, high yield, and high-volume capacity that can only be achieved by ...
Theoretical analysis of partial-spatial Q-switching dynamics using a two-level CO2 laser model Vrije Universiteit Brussel
A detailed numerical study of the dynamic behavior of a Q-switched CO2 laser under partial-spatial modulation conditions is presented. The Q-switching performance is strongly related to the switching speed and modulation depth of the modulator. The switching speed of most modulator principles are typically limited by one or more geometrical dimensions of the modulator. For example, the modulation bandwidth of an acousto optic modulator is ...

Time dependence of spatial solitons in nematic liquid crystals Universiteit Gent
Although quite a number of applications of spatial solitons can be envisaged, the main application is their use as a dynamic optical interconnection. Depending on the speed at which the optical interconnection can be redirected from one output to another, different possibilities arise. If the switching time is in the order of a second, then typically only reconfigurable interconnects are possible, e.g. protective switching (when one optical path ...
Optimalisatie van uitkomstparameters voor evaluatie van het effect van nieuwe pharmaca voor behandeling van mucoviscidose KU Leuven
Introduction Cystic Fibrosis Cystic Fibrosis (CF) is the most common severe hereditary disease in Caucasian populations, affecting approximately 1 in 3500 births. Mutations in the CFTR gene cause abnormal production and/or function of the CFTR protein, an anion channel in the apical membrane with a high expression in most cells lining the airways and the ducts of exocrine glands as the sweat gland, the pancreas or the vas deferens. The abnormal ...
