Abstract: A temperature controlled multi-channel transmitter optical subassembly (TOSA) may be used in a multi-channel optical transceiver. The temperature controlled multi-channel TOSA generally includes an array of lasers optically coupled to an optical multiplexer, such as an arrayed waveguide grating (AWG), to combine multiple optical signals at different channel wavelengths. The lasers may be thermally tuned to the channel wavelengths by establishing a global temperature for the array of lasers and separately raising local temperatures of individual lasers in response to monitored wavelengths associated with the lasers. A temperature control device, such as a TEC cooler coupled to the laser array, may provide the global temperature and individual heaters, such as resistors adjacent respective lasers, may provide the local temperatures. The optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).

Abstract: A temperature controlled multi-channel transmitter optical subassembly (TOSA) may be used in a multi-channel optical transceiver. The multi-channel TOSA generally includes an array of lasers optically coupled to an arrayed waveguide grating (AWG) to combine multiple optical signals at different channel wavelengths. A temperature control system may be used to control the temperature of both the array of lasers and the AWG with the same temperature control device, e.g., a thermoelectric cooler (TEC). The multi-channel optical transceiver may also include a multi-channel receiver optical subassembly (ROSA). The optical transceiver may be used in a wavelength division multiplexed (WDM) optical system, for example, in an optical line terminal (OLT) in a WDM passive optical network (PON).

Abstract: An optically-pumped (OP) multiple quantum well (MQW) active region is disposed in an optical cavity of an OP VCSEL, which generates laser light at a lasing wavelength. The OP VCSEL receives pump light at a first end of the optical cavity. A plurality of quantum well (QW) groups are equally spaced within the active region to correspond in position with antinodes of a standing wave of the lasing wavelength in the optical cavity. The QW groups include a first QW group that is closest to the first end of the optical cavity, and a last QW group that is farthest from the first end of the optical cavity. A plurality of equally thick intermediate absorbing layers are disposed between adjacent QW groups. A last absorbing layer is disposed adjacent to the side of the last QW group farthest away from the first end of the optical cavity. A first absorbing layer is disposed adjacent to the side of the first QW group closest to the first end of the optical cavity. The first absorbing layer has a thickness at least two times smaller than that of the intermediate absorbing layers, thereby leading to improved pump power distribution uniformity across QW groups of the active region.

Abstract: Demounting workpieces attached to an adhesive surface of an adhesive film with a workpiece demounting apparatus having a base and a plurality of substantially parallel blades mounted to the base. Each of the blades has a substantially linear blade edge, each blade edge lying within a blade-edge plane that is substantially perpendicular to the blades. The spacing between the blades is small enough to support said workpieces and large enough to permit the adhesive film to pass between the blades after being cut by said blade edges during a workpiece demounting operation. The plurality of blade edges thus provides a substantially planar blade-edge surface, in the blade-edge plane, for cutting the adhesive film and for supporting the workpieces while the adhesive film is pulled free from said workpieces.

Abstract: A multiple reflectivity band reflector (MRBR) includes a stack of dielectric layers, arranged so that the reflector has a reflectivity profile comprising a plurality of reflectivity bands, e.g. at least first and second wavelength bands with reflectivity above a lasing threshold reflectivity, separated by a third wavelength band between the first and second wavelength bands having reflectivity below the lasing threshold reflectivity. A laser having at least a first mirror and an MRBR as the second mirror has a laser cavity, at least a portion of which is defined by the first mirror and the MRBR. An active region located within the laser cavity contains a material that is capable of stimulated emission at one or more wavelengths in the first and second wavelength bands. The gain spectrum of the laser is adjusted to select one of the first and second wavelength bands, thereby providing for lasing at a wavelength within the selected wavelength band. The laser may be, e.g., a monolithic VCSEL or a one-section or two-section external-cavity VECSEL having the MRBR as one of its cavity mirrors.

Abstract: A planar lightwave circuit (PLC) module for conditioning light output from a tunable laser designed to generate light at a target wavelength. The PLC module has a substrate; a primary waveguide embedded in said substrate, said primary waveguide having an input end for receiving light from the tunable laser and an output end for outputting said light; and at least a first secondary waveguide embedded in said substrate, said first secondary waveguide receiving a first portion of said light from the tunable laser. A filter having a passband centered on the target wavelength is coupled to an output of the first secondary waveguide to receive said first portion of light, and generates a signal related to the intensity of said first portion of light in the passband centered on the target wavelength. This may be used by a processor and associated laser control circuitry for wavelength locking purposes.

Abstract: The present disclosure is generally directed to an RF connector assembly for use within a node of a broadband distribution network, and can receive a center conductor pin of a coaxial cable, e.g., via insertion by a technician, and electrically couple the center conductor pin to circuitry within the node, such as an amplifier. The RF connector assembly preferably also securely physically couples to the center conductor pin via a spring-biased arrangement (and thus by extension securely couples the coaxial cable to the housing of the node) which can supply a bias force to the center conductor pin in response to insertion of the same into the RF connector assembly. This advantageously eliminates the necessity of opening the housing of the node to couple/decouple the center conducting pin of the coaxial cable to the node.

In more detail, the transceiver housing includes at least first and second housing portions on opposite sides and forming a compartment defined by one or more inner surfaces therein. The vapor chamber includes a heat input side and a heat output side on opposite sides of the vapor chamber. An outer wall of at least one of the housing portions may be defined at least in part by the heat output side of the vapor chamber such that the heat output side is exposed to outside of the transceiver housing for transferring heat from inside to outside the optical transceiver module.

Abstract: The present disclosure is generally directed to a connector assembly that includes an increased outer diameter of the connector member relative to the equivalent G-type connector and an increased inner diameter of the receptable member relative to the equivalent G-type receptacle (also referred to as a seizure nut) to achieve higher current carrying capacity and target frequency rates of up to 3.0 Ghz, for example. In one preferred example, this results in a connector assembly consistent with the present disclosure having a connector member with an outer diameter of at least 10.70 mm, and more preferably 10.76±0.01 mm, rather than the 9.4 mm diameter of existing G-type connectors. Despite this increased diameter, a seizure assembly consistent with the present disclosure can achieve a functional impedance of 75 ohms to maintain nominal signal quality.
