摘要： Generator for wholly optical tunable broadband linearly chirped signal comprising a mode-locked laser, a first optical coupler, a first optical filter, a first dispersion module, a second optical filter, a second dispersion module, a tunable time delay module, a second optical coupler, an optical amplifier, and a photodetector. The generator of the present invention employs just one mode-locked laser as a light source, thus preventing instability of the generated signal resulting from independent unrelated lasers. By making use of the principle of wavelength-time mapping and by means of adjusting the center wavelength and the filter bandwidth of the first optical filter and the second optical filter, easy and flexible tuning of the center frequency and sweep bandwidth of the generated linearly chirped signal is realized. The present invention possesses a big advantage on the aspect of generating a broadband linearly chirped signal over other solutions.

摘要： An embodiment simultaneously receives light waves emanating from an object and having first frequency components f1.1 and f1.2, and pumped monochromatic coherent light waves having a second frequency f2. The method non-linearly combines the light waves having the first frequency component f1.1 and the pumped monochromatic coherent light waves, and generates coherent light waves having a third frequency component f3.1 that is a sum of the first frequency f1.1 and the second frequency f2. The method non-linearly combines the light waves having the first frequency component f1.2 and the pumped monochromatic coherent light waves, and generates coherent light waves having a third frequency component f3.2 that is a sum of the first frequency f1.2 and the second frequency f2. The method digitizes the generated coherent light waves and outputs an image responsive to the light waves emanating from the object.

摘要： Embodiments include an apparatus and method. An apparatus includes a metasurface that coherently upconverts light waves having a first frequency f1. A substrate forms a first plasmonic surface. A plasmonic nanoparticle forms a second plasmonic surface. A layer of a second-order nonlinear dielectric material is disposed between the first plasmonic surface and the second plasmonic surface. The metasurface has at least three plasmonic resonant modes including a first plasmonic resonant mode having a first frequency f1, a second plasmonic resonant mode having a second frequency f2, and a third plasmonic resonant mode having a third frequency f3 that is a sum of the first frequency f1 and the second frequency f2. The apparatus includes a second light propagation path from a source of pumped monochromatic coherent light waves having the second frequency f2 to the metasurface. A digital image capture device captures the generated light waves having the frequency f3.

摘要： Embodiments herein provide for an optical frequency reference including a fine optical frequency comb and a coarse optical frequency comb. The fine comb has a first tooth and a frequency spacing (FCS) between teeth that is locked to a fractional or integer multiple of a radio frequency reference. The coarse comb has a second tooth that is locked to the first tooth and a frequency spacing (CCS) between teeth that is locked to an integer multiple of the FCS. An absolute optical frequency of at least one tooth of the coarse optical frequency comb is set.
