  • Patent number: 12027811
    Abstract: The present invention provides octave-spanning optical frequency combs. The octave-spanning optical frequency combs employ microresonators having improved stability using a smaller form factor. In some embodiments, the octave-spanning optical frequency combs are fabricated using aluminum nitride (AlN). AlN is a more robust Kerr material for generating octave-spanning soliton comb (e.g., 1.5 octaves or more).

  • Patent number: 10800915
    Abstract: A polycarbonate composition includes the following components in parts by weight: a. 30 to 87 parts of a PC resin; b. 8 to 50 parts of a rubber-modified graft polymer; c. 5 to 25 parts of a fire retardant; and d. 0 to 10 parts of other aids; wherein a sum of parts by weight of the four components a, b, c, and d is 100. Phenols which are added in a polycarbonate composition formula, based on a total weight of the polycarbonate composition does not exceed 100 ppm. A K value of a component I of the PC resin is adjusted between 300000 and 500000 and the K value of a component II is adjusted to be less than 300000.
