摘要： Systems and methods for biasing an externally modulated laser. An inductorless bias T network is provided that includes a terminating resistor in series with a capacitor. The capacitor is an open circuit for a bias signal and a virtual ground for an RF signal. Thus, the RF signal is terminated by the terminating resistor without dissipating the bias signal through a ground return path of the RF signal. Using a charge pump inverter, a positive supply can be used to positively bias a laser and negatively bias the external modulator through the terminating resistor. A negative power supply is not required. A swing voltage provided by the RF signal causes the external modulator to modulate the light emitted by the laser.

摘要： An optoelectronic assembly includes a circuit board having a set of signal traces, where one or more of the signal traces has a junction point that integrates a pad of a circuit element. Exemplary circuit elements include a resistor, capacitor, and an inductor. The junction point has a first width and a first thickness, and the one or more signal traces have a second width and a second thickness. The dimensions of the junction point and the dimensions of the one or more signal traces are configured such that the first width and the second width are substantially similar, and that the first thickness and the second thickness are substantially similar. In one embodiment, the first width is no greater than 125% of the second width.

摘要： A transceiver module is provided that includes an optical subassembly having an extension with traces corresponding to traces defined on an associated transceiver substrate. A connector element including a flexible, non-electrically conductive substrate within which is disposed an array of conductors is placed between overlapping portions of the extension and the transceiver substrate so that upper ends of some of the conductors contact the traces of the extension, while lower ends of those same conductors contact the corresponding traces of the transceiver substrate. In this way, the connector element provides electrical communication between the optical subassembly and transceiver substrate, while also accommodating misalignment that may be present, or develop, in the transceiver module components.

摘要： A sleeve apparatus for protecting a robotic kitchen arm from contamination. The sleeve includes a proximal end, a distal end, a passageway extending from the proximal end to the distal end, and an exterior surface. The passageway has an effective diameter less than the effective diameter of the robotic kitchen arm such that the exterior surface of the sleeve apparatus is substantially fold-free when the robotic arm is in the extended configuration. Methods of cleaning a robotic kitchen arm are also described.
