Opis:: The paper is a review and comparative analysis of most common techniques proposed to attach additional data or identification information to digital signals in optical fiber networks by purely optical means. Such "labels" or "headers" can be attached either to continuous bit streams, e.g., in SDH networks or to optical packets. They enable to monitor, route and identify signals in transparent optical networks, especially those with optical wavelength multiplexing, allow management and supervision of remote optical amplifiers and can be used in optical switching systems. Other applications of this relatively unknown technology include monitoring of optical path dispersion, equalization of channels in DWDM systems and detection of intrusion or jamming in highly secure networks.

Opis:: Despite the advances in optical biosensors, the existing technological approaches still face two major challenges: the inherent inability of most sensors to integrate the optical sourc e in the transducer chip, and the need to specifically design the optical transducer per application. In this work, the development of a radical optoelectronic platform is demonstrated based on a monolithic optocoupler array fabricated by standard Si-technology and suitable for multi-analyte detection. The platform has been specifically designed biochemical sensing. In the all-silicon array of transducers, each optocoupler has its own excitation source, while the entire array share a common detector. The li ght emitting devices (LEDs) are silicon avalanche diodes biased beyond their breakdown voltage and emit in the VIS -NIR part of the spectrum. The LEDs are coupled to individually functionalized optical transducers that converge to a single detector for multiplexed operation. The integrated nature of the basic biosensor scheme and the ability to functionalize each transducer independently allows for the development of miniaturized optical transducers tailored towards multi -analyte tests. The monolithic arrays can be used for a plethora of bio/chemical interactions becoming thus a versatile analytical tool. The platform has been successfully applied in bioassays and binding in a real -time and label-free format and is currently being applied to ultra-sensitive food safety applications.

Opis:: Scalability of packet switched cross-connects that utilize all-optical signal processing is a crucial issue that eventually determines the future role of photonic signal processing in optical networks. After reviewing several labeling techniques, we discuss label stacking and label swapping techniques and their benefits for scalable optical packet switched nodes. All-optical devices for implementing the packet switch based on the labeling techniques will be described. Finally, we present a 1×4 all-optical packet switch based on label swapping technique that utilizes a scalable and asynchronous label processor and label rewriter. Error-free operation indicates a potential utilization of the swapping technique in a multihop packet-switched network.

Opis:: In this work, we review microcavity in-line Mach-Zehnder Interferometers (µIMZI) obtained in optical fibers using femtosecond (fs) laser micromachining. These structures can be considered as a great solution satisfying the requirements mentioned above for small-volume RI sensing applicable in label-free biosensing. Furthermore, application of the femtosecond laser facilitates tailoring of the microcavity’s shape with high degree of flexibility. Over the years, various µIMZI have been reported, where RI sensing has been mainly analyzed but no impact of the microcavity shape has been shown up to date. Thus, on top of the review on µIMZIs, in this work, we discuss the impact of the shape of the on the sensing performance of the device. We use two representative examples of microcavity shapes, i.e., U-shape and V-trench, made in a standard single-mode fiber. Despite different shapes, both structures offer similar and high RI sensitivity (exceeding 13,000 nm/RIU in the RI range 1.333–1.340 RIU). However, the performance of the structures in microfluidic systems is different. Based on the experimental results and numerical simulations, the advantages and disadvantages of different shapes are discussed for their application in investigations of liquids and biosensing.
