Hybrid plasmonics can provide a technology solution for lab-on-a-chip applications with nano-scale waveguiding and subwavelength light confinement, keeping the propagation loss on an acceptable level. In this talk we will present some designed and fabricated devices in application to bio-sensing, based on single-slot and double-slot hybrid plasmonic resonant structures on silicon platform that can...
Optical performance monitoring (OPM) is desired for future smart optical networks. 2-D phase portrait contains fruitful waveform information, which can be a valuable tool for OPM. In this paper, we review the generation of 2-D phase portrait by our cost-effective single-channel sampling technique, and its applications for OSNR and dispersion monitoring in different systems.
In this contribution a multiwavelength erbium ring laser is presented. The multiwavelength operation isachievedby using a novel in-line Mach-Zehnder (MZ) fibre interferometer based on multicore microstructured fibre (MC-MOF).The MZ interferometer acts as a periodic spectral filter. The modal properties of the MC-MOF are analysed using the finite difference method. Dual wavelength operation is demonstrated...
Recent advances in the theoretical and experimental studies of Ge/SiGe quantum wells structures will be presented with a focus on optical telecommunication applications. Firstly, high-speed stand-alone Ge/SiGe QW electro-absorption modulators and photodetectors will be reported. It will be followed by the presentation of different methods for engineering Ge/SiGe QW to tune the operating wavelength...
Low-Coherence Interferometry (LCI) is a highly relevant optical measurement technique used in a wide variety of applications from sensing to medical imaging among others due to its non-invasive performance with high axial precision. In this work, a novel structure is proposed with the application of Microwave Photonics (MWP) as key enabling technology for real-time LCI applications. The proposed MWP-LCI...
The mode-division multiplexing is recognized as an effective solution for increasing the capacity of the optical communication systems. In view of short-distance applications, as data communication intra and inter data centres, where cost, complexity and power consumption are fundamental issues, a passive optical technique for mode demultiplexing can allow for realizing mode-division multiplexing...
We demonstrate the use of back focal plane interferometry for the measurement of the forces felt by a trapped sphere moving inside a hollow photonic crystal cavity. The presence of two trapping regimes, one of these being a back-action effect, is observable in concordance to previous observations. We also demonstrate that particle can be differentiated by size with the monitoring of the light transmitted...
We propose and analyse two novel mesh design geometries, the hexagonal and the triangular lattice, for the implementation of tunable optical cores in programmable photonic processors and universal couplers. They are compared to a previously proposed square mesh topology in terms of a series of figures of merit that account for metrics that are relevant to on-chip integration of the mesh finding that...
This paper presents an all optical packet forwarding architecture composed of two optical logical gates namely the XOR gate and the AND gate. Error free operation is achieved at 160 Gbps for the AND logic gate as well as the forwarding architecture. And clear eyes diagrams are obtained.
