Clinical reports regarding the use of the ALGO2 neonatal automated auditory brainstem response (AABR) screening device have been concerned only with issues of sensitivity and specificity. This study was undertaken to evaluate how couplers and their placement affect the ALGO2 click spectral properties. Although not recommended by the manufacturer, substituting less expensive, uncalibrated couple...

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...
