摘要: A device includes a waveguide grating out-coupler, and a tunable uniform phase shifter communicating with the waveguide grating out-coupler. The tunable uniform phase shifter steers a flat phase front along a first angle in a first plane. Optionally, the waveguide grating out-coupler includes a modulated refractive index and a physical grating period. The tunable uniform phase shifter controls the refractive index, thereby controlling an effective grating period. The grating period relates to the modulated refractive index, and the physical grating period. Optionally, the tunable uniform phase shifter includes a first thermo-optic phase shifter, a first electro-optic phase shifter, or a first micro-electro-mechanical system index perturbation phase shifter. Optionally, the tunable linear gradient phase shifter communicates with the waveguide grating out-coupler and steers a beam along the flat phase front along a second angle in a second plane, which is perpendicular to the first plane.

摘要: An optical waveguide comprises multiple layers of solid-state material disposed on a substrate. One of the layers is a lifting-gate valve made of a high refractive index material. The device provides for better optical confinement in microfluidic channels, and has the capability to integrate both optical signals and fluid sample processing. The optical paths on the chip are reconfigurable because of the use of a movable microvalve that guides light in one of its positions.

摘要: Light is directed from a light source at a coupling surface of a slider into a delivery waveguide of the slider. The delivery waveguide couples a first portion of the light into a near-field transducer at a media-facing surface. A second portion of the light is coupled into a splitter waveguide. The second portion of light is detected to perform an active alignment of the light source on the slider.

摘要: A light system may include a fused mid-IR tapered combiner to optically connect a bundle of mid-IR fiber bundles with a multimode fiber. The fused mid-IR fiber tapered combiner arranges a bundle of fibers in a geometric arrangement to reduce the diameter of a plurality of mid-IR fibers to match or equal the diameter of a single multimode mid-IR fiber. The mid-IR fibers carry light produced and emitted from semiconductor light sources.

摘要: This invention removes the need to provide temperature control for an optical time delay chip, which is usually provided by a thermo-electric-cooler, in order to significantly reduce the power dissipation of the device and allow ‘uncooled’ operation. Uncooled operation is achieved by monitoring the temperature of the chip, and changing the tuning of each microresonator within the device in order to continue providing the required time delay as the temperature is varied. This invention takes advantage of the fact that microresonators provide a series of resonant wavelengths over a wide wavelength range, so that the closest resonance wavelength below the operating wavelength can always be tuned up to that wavelength. When the device temperature changes, this is accounted for by both the choice of resonance wavelengths and the tuning for each of the microresonators in the device, in order to keep the correct tunable delay.
