Planar waveguide junctions are described with a waggled transition section connecting input waveguide sections with output waveguides sections, in which the waggled transitions have alternating segments matching the input waveguide and output waveguides to efficiently transition the optical signal. The planar waveguide junctions can be used to form efficient optical splitters, mixers, or taps.

Planar lightwave circuit optical splitter/mixer

A multiple-output laser component is described with a plurality of diode lasers in a common package, each of the diode lasers having distinct electrical control and optically coupled to a distinct output fiber, the component configured such that up to a maximum total output power can be selectively and dynamically partitioned among said diode lasers. The dynamic allocation can be based on demand for laser power in a fiber optic coupled to each diode laser. The multi-output laser component can be used to drive amplifiers associated with a multicast switch in some embodiments.

Telecommunications switches are presented, including expandable optical switches that allow for a switch of N inputs&#xd7;M outputs to be expanded arbitrarily to a new number of N inputs and/or a new number of M outputs. Switches having internal switch blocks controlling signal bypass lines are also provided, with these switches being useful for the expandable switches.

A method of operation of an optical network communication system including: providing a planar lightwave circuit including: connecting 2&#xd7;2 single-mode optical couplers in an array for forming a 1&#xd7;N single-mode optical splitter/combiner, and routing harvesting ports to an optical line terminal receiver for collecting harvested-light, from two or more of the harvesting ports, in the optical line terminal receiver wherein one of more of the harvesting ports is from the 2&#xd7;2 single-mode optical couplers; transmitting to an optical network unit through the planar lightwave circuit at a first wavelength; and interpreting a response from the optical network unit at a second wavelength through the harvested-light.

A method of manufacture of an integrated circuit coupling system includes: forming a waveguide assembly, having a top clad over an open end of an optical core; forming a first photoresist having a base photoresist pattern shape with sloped photoresist sidewalls tapered down to expose a portion of the top clad; forming a recess having clad sidewalls from the portion of the top clad exposed by the base photoresist pattern shape, the clad sidewalls having a shape replicating a shape of the base photo resist pattern shape; and forming an optical vertical insertion area, from the clad sidewalls forming the recess, having a pocket trench, a horizontal step, and a mirror with a reflective material selectively applied to a section of the clad sidewalls and exposing the open end opposite to the mirror, the horizontal step between the mirror and the pocket trench.

Arrayed waveguide grating can have one or both slab waveguides with relatively sharply folded optical paths and a mirror that provides the folding of the path. The folded optical paths through the slab waveguides can result in a more compact geometry of the waveguides through the device as well as smaller slab waveguides such that the device can be formed with a significantly smaller overall footprint. Also, arrayed waveguide gratings that cooperate with pivotable mirrors can adjust light passage through the waveguide in response to temperature changes to provide for thermally compensated operation of the device. Thus, very compact planar lightwave circuits filters are described that provide thermally compensated operation.

A method, a system, and a computer program product for managing one or more electronic devices. Performance of an electronic device is monitored and presented to a user through a digital agent interface. The performance of the electronic device is controlled automatically by digital agent through the digital agent interface. The invention also enables automatic testing of the electronic device through the digital agent interface by setting up test configurations, activating test signals, and interpreting any error codes that may be generated.

Monitoring and control of electronic devices

Optical networks can comprise a branch structure with the de-multiplexing/multiplexing structure that operates to disperse a plurality of optical bands. Thus, the optical network comprises an optical network connection with a common optical channel, a plurality of de-multiplexed branch optical service connections and the de-multiplexing/multiplexing structure. In some embodiments, one optical band can be used to deliver input from a common channel to the branch node and the other optical band can carry output along the common channel from the branch node. The de-multiplexing/multiplexing element can be an arrayed waveguide grating. The AWG can have desirable architecture to efficiently provide the corresponding functions with respect to the two optical bands. Appropriate photodetectors and light sources can be associated with the AWG.

Methods of using an optical device capable of distributing the optical power presented at an input to specified ratios in two output ports. The devices and methods described herein have the ability to broaden the range of wavelengths over which the splitting ratio is even, or substantially even. Methods involve achieving a desired splitting ratio over a broad or ultra-broad wavelength range.
