摘要： Some embodiments include a light source, optical fiber, photonic integrated circuit (PIC) components (e.g., ridge waveguide, tapered waveguide, ring resonator, Mach-Zehnder, array waveguide grating, input/output grating coupler), and the refractive and diffractive optical components (e.g., diffractive lens, gratings, metasurface-based lenses, refractive lenses, diffractive grating, surface relief grating, sub state, liquid crystal) to control, shape, sort, and guide the light toward a desired direction and ultimately focus it into an object for imaging and/or illumination. Further, embodiments may include at least one optical source, at least one sensor, and at least one control module. The control module may control, tune, and adjust the functionality of each component depending on feedback from the sensor or user. The functionality of some components can be dynamically changed by applying an electric voltage and/or current or changing the properties of impinging light (e.g., polarization, wavelength).

摘要： A phase correction concept is introduced to improve the performance of a spatially multiplexed optic. In a specific example, the optic is a diffractive lens. A phase offset is added to extend the depth of field of the diffractive lens and increase its focusing intensity. This can result in increased signal-to-noise ratio. These diffractive lenses may be used for imaging, focusing, and/or delivering light to an area of interest. They may be used to realize miniaturized medical imaging based on different imaging modalities such as optical coherence tomography, Raman spectroscopy, and fluorescence microscopy. They may also be used for different purposes and applications, for example laser ablation.

摘要： Several configurations of optical systems are disclosed herein. In some embodiments, the optical system includes a substrate having a first surface and a second surface, and a first reflector disposed on the substrate and configured to receive light. The light includes at least one of a first wavelength of light and a second wavelength of light. The first reflector is configured to reflect the first wavelength of light along a first light path toward a first diffractive lens and to transmit the second wavelength of light toward a second reflector. The second reflector is configured to reflect the second wavelength of light along a second light path toward a second diffractive lens.
