摘要： A novel, monolithically integrated mid-IR optical phased array (OPA) structure which eliminates the wafer bonding process to achieve highly efficient surface emitting optical beam steering in two dimensions is disclosed. Since solar energy is about 15-20 times smaller than that at 1.55 μm, mid-IR is more favorable for the atmospheric transmission due to lower solar radiance backgrounds. For the beam steering, thermo-optic phase shifting is used for azimuthal plane beam steering and laser wavelength tuning is used for elevation plane beam steering. The OPA structure disclosed comprises a wavelength-tunable a QCL, a 1×32 splitter, thermo-optic phase-shifters, and sub-wavelength grating emitters. The disclosed OPA provides a low-cost, low-loss, low-power consumption, robust, small footprint, apparatus that may be used with expendable UAV swarms. A LiDAR may be created by monolithically integrating a QCD with the apparatus. Other embodiments are described and claimed.

摘要： An active device for dynamic control of lightwave transmission properties has at least one photonic crystal waveguide that has anti-reflection photonic crystal waveguides with gradually changed group refractive indices at both input and output side. An alternating voltage or current signal applied to two electrically conductive regions changes the refractive indices of the photonic crystal materials, introducing a certain degree of blue-shift or red-shift of the transmission spectrum of the photonic crystal waveguide. The output lightwave with frequency close to the band-edge of the photonic crystal waveguide is controlled by the input electric signal. Devices having one or more such active photonic crystal waveguides may be utilized as an electro-optic modulator, an optical switch, or a tunable optical filter.

摘要： An active device for dynamic control of the transmission properties has at least one photonic crystal waveguide that has an electrically insulating layer formed within or near the waveguide core and two lateral conductive regions divided by the insulating layer. An alternating voltage signal induces phase and amplitude changes of electromagnetic wave propagating inside the device. Electromagnetic wave signals propagating through two such active photonic crystal waveguide devices may be mixed to produce at least one output signal through interference. Devices having one or more such active photonic crystal waveguides may be utilized as a tunable optical delay line, a tunable optical filter, a switch, or a modulator. A preferred embodiment comprises a photonic crystal waveguide made of a silicon slab with a periodic array of apertures or oxide columns therein, wherein an silicon oxide layer disposed in the waveguide core separates a p-doped region from an n-doped region.
