Abstract: A beam-steering device (100) for spatial steering of a light beam comprises a waveguide array (10) being arranged on a substrate (50) and comprising a waveguide array input (12), multiple waveguides (14-1, 14-2, . . . , 14-i) and a waveguide array output (16), wherein the multiple waveguides (14-1, 14-2, . . . , 14-i) are adapted for simultaneously guiding light from the waveguide array input (12) to the waveguide array output (16) and for forming a light beam downstream of the waveguide array output (16) by superimposing the light guided by the waveguides (14-1, 14-2, . . . , 14-i), a phase shifter device (18) being arranged for applying controlled phase shifts to the light guided in each of the waveguides (14-1, 14-2, . . .

Abstract: A photodetector apparatus (100), being configured for detecting light in the visible or infrared spectrum, comprises a substrate (30), a waveguide (20), a detector section (10), a first contact section (50) and a second contact section (52). The substrate (30) has a substrate surface (32) and a cladding layer (40). The waveguide (20) is arranged above the substrate surface (32) in the cladding layer (40) and is adapted for guiding light. The detector section (10) comprises a p-doped region (12, 14) and an ndoped region (16, 18), and the detector section (10?) is arranged for producing charge carriers by the (10) light guided in the waveguide (20). The first contact section (50) is connected to the p-doped region (12, 14) and the second contact section (52) is connected to the n-doped region (16, 18), the first and second contact sections (50, 52) being connectable to a measuring device for measuring an electrical signal based on the charge carriers produced by the light.

Abstract: One embodiment relates to a sink system having an air recirculating mechanism for exhausted hand dryer air. The sink system includes a sink deck having a sink opening and an outer shell. The sink deck being separated from a sink basin region of a sink basin by a vent ring. A sink basin defines a sink basin region and a plenum region. The plenum region is separated from the sink basin region by the vent ring. A plenum cavity is formed between an internal surface of the outer shall and the plenum region. The vent ring includes a vent with an associated opening. The opening is exposed to the sink basin region and to an area underneath the sink deck, the opening allowing a flow of air therethrough. A dryer is configured to direct forced air through a dryer exhaust port into the sink basin region of the sink basin.
