Abstract: A first waveguide and a second waveguide are aligned by applying an alignment dot on end surfaces of the cores of first and second waveguides. The alignment dots are positioned in close proximity to one another, and are melted together. Surface tension pulls the first and second waveguides into alignment.

Abstract: A pump comprises a chamber with an inlet and an outlet. A first heating element is located in proximity with the inlet, and a second heating element is located in proximity with the outlet. The first and second heating elements are configured when heated to form a bubble within the chamber. By controlling the first and second heating elements, fluid is expelled from the pump.

Abstract: A photonic via is made in a substrate by making a hole in the substrate, heating the substrate, and inserting a fiber optic into the hole. In one embodiment, a lens can be made by applying a polymer on top of the photonic via and curing.

Abstract: A semiconductor substrate with integrated circuit devices on its front side and a high thermal conductivity layer such as diamond on its back side, with components such as capacitors embedded in the high thermal conductivity layer and coupled to the front side integrated circuits with vias through the substrate.

Abstract: A thermally wavelength tunable laser having selectively activated gratings includes a core, more than one periodic arrangement adjacent to the core, and thermo-optical material adjacent to each periodic arrangement. At an off temperature, the refractive index of the periodic arrangement and the adjacent thermo-optical material is the same. By selectively changing the temperature and hence the refractive index in the thermo-optical material adjacent to a selected periodic arrangement, the selected periodic arrangement forms a diffraction grating which can be tuned over a selected wavelength range. By selecting different periodic arrangements, different, non-overlapping wavelength ranges can be selected and the laser can be tuned over a broad range of wavelengths.

Abstract: A lithographic process is used to place a marking on a waveguide to indicate optical channels within the waveguide. A photonic component is positioned against the waveguide based on the markings and adjusted until aligned.

Abstract: A device and method of aligning two or more optical fibers on an array waveguide is achieved by etching grooves into the array waveguide. The two or more optical fibers are attached together by a retainer and placed into the grooves of the array waveguide. Channels within the array waveguide are coursely aligned to the two or more optical fibers and may be more finely aligned by manual adjustment.

Abstract: A device has both electronic and photonic components on a shared substrate. The electronic components may include a light source for providing a photonic signal around the substrate to the photonic components.

Abstract: A data segment is provided with minimal access latency. The data segment is divided into three or more portions and provided via two or more channels. Each of the channels carries a portion of the data segment, the portion of the data segment carried by each channel being less than the entire data segment. Each of the channels repeat over time. In one embodiment, the two or more channels are physical channels. In another embodiment, the two or more channels are logical channels which are time-multiplexed over a single physical channel.

Abstract: A method of controlling the transfer of data between a first and a second computer network comprises parsing content description language received from the first computer network by the second computer network to determine current tag information within the content description language. A completion decision is then dynamically made based upon the current tag information. In one embodiment, the completion decision may include any of the following: full data transfer between the two networks, partial data transfer between the two networks, a deferred data transfer at a later time, or a cached data transfer. Restrictions based upon a user's age, a user's access rights, cost, system resources, and time of day may also be employed to limit the transfer of data based upon the current tag information. In a preferred embodiment, the content description language is HTML. This method may be practiced by an application level proxy that is part of a firewall system protecting the second computer network from the first.

Abstract: Index prediction is used to access data in a memory array. A virtual address is received at an input. The virtual address is translated to a physical address. The memory array is accessed at a predicted address. A portion of the predicted address is compared to a portion of the physical address. If the portion of the predicted address is different from the portion of the physical address, then the predicted address was an incorrect prediction. The memory array is accessed at the physical address.

Abstract: Preventing processor domination of a CPU by background transfers of teleconference object data during an electronic conference is accomplished by monitoring an external time spent by a CPU executing outside a background transfer manager. Transfers of data packets of teleconference object data are performed if the external time is larger than a minimum threshold and smaller than a maximum threshold.
