Abstract In this paper, we report, for the first time, a theoretical study on passive photonic devices including optical power splitters/combiners and grating couplers operating at non-telecom mid-wave infrared wavelengths. Passive components were designed to operate, in particular, around 2.6 µm monolithic integration with active III-V gallium antimonide material platform. The three popular ty...

Abstract The Shanghai High Repetition Rate XFEL and Extreme Light Facility (SHINE) project will use 600 1.3 GHz fundamental power couplers, which are modified based on TTF-III for continuous-wave operation with input up to approximately 7 kW. first batch of 20 sets coupler prototypes was fabricated from three domestic manufacturers the SHINE project. To better characterize radio frequency condi...

Introduction. Russian manufacturers currently produce screw-threaded reinforcing bars (rebars) and couplers to join them. However, the application of such reinforcement in construction industry is hindered by a high compliance screw couplings. Aim: assess coupling joints reinforced with adhesives. Materials methods. The study used Av500P rebars, couplers, as well adhesive compounds containing c...

A vertical directional coupler fabricated using wafer fusion is demonstrated with a very short coupling length of 62 mm. The optical propagation loss introduced by the fused layer is investigated. An excess loss of 1.1 dB/cm at 1.55 mm was measured for waveguides which incorporate a fused junction near the core region. Fused vertical couplers make it possible to realize three-dimensional wavegu...

It provides a simple, convenient, accurate means for sampling microwave energy without moving parts and without the need for adjustments. Unlike other met...

A novel design of all-optical logic gates based on nonlinear slot waveguide couplers is proposed. NOT, OR, and AND logic gates can be realized by simple single optical directional coupler configuration. Strong polarization dependencies of slot waveguides are effectively utilized for realizing polarization-independent optical directional couplers in linear regime and polarization-dependent all-o...

This presentation includes a short overview of integrated optics and a more detailed description of a realized optical beam combiner circuit for a space optic application. The introduction covers the basics of straight and bent waveguides, crossings and couplers. Integration of waveguides with fibers, lasers, detectors and electronics is briefly described, as well as the main differences betwee...

We consider an analogue of entanglement-swapping for a set of black boxes with the most general non-local correlations consistent with relativity (including correlations which are stronger than any attainable in quantum theory). In an attempt to incorporate this phenomenon, we consider expanding the space of objects to include not only correlated boxes, but ‘couplers’, which are an analogue for...
