Abstract: An optical waveguide has a window for receiving optical signals re-directed by a beam splitter and a heating element associated with the window.

Abstract: A system includes an external light supply to a silicon photonic chip. The light supply includes a primary light source, a secondary light source, an optical coupler, an optical splitter, and a dark sensor. The optical coupler is to combine any output from the primary light source and any output from the secondary light source into an input to the silicon photonic chip. The optical splitter is located in an optical path between the primary light source and the optical coupler, and is to divert part of the output from the primary light source. The dark sensor is to receive the diverted part of the output from the primary light source and to selectively activate the secondary light source based on the diverted part of the output from the primary light source.

Abstract: Example methods and apparatus to remove dust from an optical waveguide assembly are disclosed. An example apparatus includes a window to be located on an optical waveguide assembly. The example apparatus includes a first piezoelectric member coupled to the window. The first piezoelectric member is to vibrate the window to remove dust from the window in response to an electrical signal.

Abstract: In one implementation a device connector includes a first electronic device magnet, second electronic device magnet, and third electronic device magnet to connect to a power supply. The power supply magnet can be oriented to the opposite pole of one of the electronic device magnets.

Abstract: A network device including a power supply, a communication port and a power line between the power supply and the communication port. A controller is to turn on a switch so that power can be delivered to the communication port along a second power line parallel to the first power line, before sending a power down signal.
