  • Publication number: 20230197208
    Abstract: A computer implemented method of modifying molecular structures constrained by a budget is provided. The computer implemented method includes receiving from a user a subset of molecules, where each molecule is represented as a generation path, and receiving from the user an allotted budget for modifying a selection of molecules from the subset of molecules. The computer implemented method further includes testing a first molecule, and reducing the allotted budget based on the resources expended to test the first molecule. The computer implemented method further includes testing a second molecule, and reducing the allotted budget based on the resources expended to test the second molecule. The computer implemented method further includes determining a remaining amount of the allotted budget, and testing additional molecules from the subset of molecules until the allotted budget is exhausted. The computer implemented method further includes presenting the tested molecules to the user.

  • Patent number: 10365425
    Abstract: A method for fabricating an optical waveguide crossing structure. The method includes preparing a plate structure including a crossing part array and a guiding part array, each crossing part of the crossing part array being arranged at a gap from a plurality of guiding parts of the guiding part array. The method further includes preparing a waveguide structure including a first waveguide core array, a second waveguide core array and a tank, the tank being formed by removing a crossing region of the first waveguide core array and the second waveguide core array. The method further includes injecting an underfill into the tank. The method further includes depositing the plate structure on the waveguide structure so that the crossing part array and the guiding part array are inserted in the tank. The method further includes curing the underfill.
