摘要： An integrated optical beam steering device includes a planar dielectric lens that collimates beams from different inputs in different directions within the lens plane. It also includes an output coupler, such as a grating or photonic crystal, that guides the collimated beams in different directions out of the lens plane. A switch matrix controls which input port is illuminated and hence the in-plane propagation direction of the collimated beam. And a tunable light source changes the wavelength to control the angle at which the collimated beam leaves the plane of the substrate. The device is very efficient, in part because the input port (and thus in-plane propagation direction) can be changed by actuating only log2 N of the N switches in the switch matrix. It can also be much simpler, smaller, and cheaper because it needs fewer control lines than a conventional optical phased array with the same resolution.

摘要： Multimode interference can be used to achieve ultra-high resolving powers (e.g., Q>105) with linewidths down to 10 pm at 1500 nm and a broad spectroscopy range (e.g., 400-2400 nm) within a monolithic, millimeter-scale device. For instance, multimode interference (MMI) in a tapered waveguide enables fine resolution and broadband spectroscopy in a compact, monolithic device. The operating range is limited by the transparency of the waveguide material and the sensitivity of the camera; thus, the technique can be easily extended into the ultraviolet and mid- and deep-infrared spectrum. Experiments show that a tapered fiber multimode interference spectrometer can operate across a range from 500 nm to 1600 nm (B=1.0576) without moving parts. The technique is suitable for on-chip tapered multimode waveguides, which could be fabricated in high volume by printing or optical lithography, for applications from biochemical sensing to the life and physical sciences.

摘要： A method includes applying, to a sample exhibiting optical scattering and having a emission particles distributed therein that exhibit spin-dependent fluorescence, a magnetic field to shift a resonance frequency of each emission particle in a position-dependent manner. The method also includes exciting the sample with an excitation beam that causes at least one emission particle to emit spin-dependent fluorescence and detecting the emitted spin-dependent fluorescence. The method also includes estimating a position of the emission particle(s) within the sample based on the spin-dependent fluorescence, the resonance frequency, and the magnetic field. The method also includes estimating optical transmission information for the sample based on a wavefront of the excitation beam and the estimated position. The optical transmission information including a measure of an optical field at each position of an emission particle.

摘要： Nitrogen vacancies in bulk diamonds and nanodiamonds can be used to sense temperature, pressure, electromagnetic fields, and pH. Unfortunately, conventional sensing techniques use gated detection and confocal imaging, limiting the measurement sensitivity and precluding wide-field imaging. Conversely, the present sensing techniques do not require gated detection or confocal imaging and can therefore be used to image temperature, pressure, electromagnetic fields, and pH over wide fields of view. In some cases, wide-field imaging supports spatial localization of the NVs to precisions at or below the diffraction limit. Moreover, the measurement range can extend over extremely wide dynamic range at very high sensitivity.

摘要： Optical microcavity arrangements and approaches facilitate a variety of applications. According to an example embodiment of the present invention, an optical microcavity arrangement includes a microcrystal structure having a plurality of optical cavities therein to facilitate the control of light. Emitters such as colloidal quantum dots are optically coupled to the optical cavities by attaching or otherwise arranging a material, which includes the emitters, to the optical microcavity arrangement. In many applications, the emitters couple photons of a wavelength in a range of wavelengths selectively passed by the optical cavities, and are amenable to operation at relatively high temperatures (e.g., at about room temperature or higher), which is useful for a variety of applications.

摘要： Most artificial neural networks are implemented electronically using graphical processing units to compute products of input signals and predetermined weights. The number of weights scales as the square of the number of neurons in the neural network, causing the power and bandwidth associated with retrieving and distributing the weights in an electronic architecture to scale poorly. Switching from an electronic architecture to an optical architecture for storing and distributing weights alleviates the communications bottleneck and reduces the power per transaction for much better scaling. The weights can be distributed at terabits per second at a power cost of picojoules per bit (versus gigabits per second and femtojoules per bit for electronic architectures). The bandwidth and power advantages are even better when distributing the same weights to many optical neural networks running simultaneously.

摘要： A buffer layer is employed to fabricate diamond membranes and allow reuse of diamond substrates. In this approach, diamond membranes are fabricated on the buffer layer, which in turn is disposed on a diamond substrate that is lattice-matched to the diamond membrane. The weak bonding between the buffer layer and the diamond substrate allows ready release of the fabricated diamond membrane. The released diamond membrane is transferred to another substrate to fabricate diamond devices, while the diamond substrate is reused for another fabrication.

摘要： Systems, apparatus, and methods using an integrated photonic chip capable of operating at rates higher than a Gigahertz for quantum key distribution are disclosed. The system includes two identical transmitter chips and one receiver chip. The transmitter chips encode photonic qubits by modulating phase-randomized attenuated laser light within two early or late time-bins. Each transmitter chip can produce a single-photon pulse either in one of the two time-bins or as a superposition of the two time-bins with or without any phase difference. The pulse modulation is achieved using ring resonators, and the phase difference between the two time-bins is obtained using thermo-optic phase shifters and/or time delay elements. The receiver chip employs either homodyne detection or heterodyne detection to perform Bell measurements.

摘要： A spatial light modulator (SLM) comprised of a 2D array of optically-controlled semiconductor nanocavities can have a fast modulation rate, small pixel pitch, low pixel tuning energy, and millions of pixels. Incoherent pump light from a control projector tunes each PhC cavity via the free-carrier dispersion effect, thereby modulating the coherent probe field emitted from the cavity array. The use of high-Q/V semiconductor cavities enables energy-efficient all-optical control and eliminates the need for individual tuning elements, which degrade the performance and limit the size of the optical surface. Using this technique, an SLM with 106 pixels, micron-order pixel pitch, and GHz-order refresh rates could be realized with less than 1 W of pump power.
