Each of the first cladding film and the second cladding film include the other of (1) the material having the index of refraction nM and (2) the alternating layers nTM<nM<nTE, and the indices of the upper cladding and the lower cladding are less than nTM, nM and nTE. A polarizer, polarizing beam splitter and coupler using clipped coupling can employ the material having an index nM and the alternating layers.Type: ApplicationFiled: December 10, 2018Publication date: July 4, 2019Inventors: JEFFREY CHILES, SASAN FATHPOUR

Publication number: 20190204505Abstract: A microelectronic device includes a photonic die having a die input/output (I/O) port. The microelectronic device includes a photonic connection between the first photonic I/O port and the second photonic I/O port. The photonic connection has a dielectric signal pathway for a photonic signal from the first photonic I/O port to the second photonic I/O port. The second photonic I/O port may be a package photonic I/O port at an exterior of the microelectronic device, or may be another die photonic I/O port on another photonic die of the microelectronic device. The photonic connection is formed using at least one additive process, such as by selectively placing material for the photonic connection in a region for the photonic connection.Type: ApplicationFiled: December 30, 2017Publication date: July 4, 2019Applicant: Texas Instruments IncorporatedInventors: Benjamin Stassen Cook, Daniel Lee Revier

Publication number: 20190204506Abstract: A polymer waveguide/modulator including a lower cladding layer, a polymer core, an upper cladding layer, a first protection/barrier layer sandwiched between the lower cladding layer and the core, and a second protection/barrier layer sandwiched between the core and the upper cladding layer. The protection/barrier layers designed to protect the cladding layers and the core from solvents and gases and to prevent current leakage between the cladding layers and the core. The first protection/barrier layer is optically transparent and designed with a refractive index less than, greater than, or the same as the refractive index of the core and approximately equal to the refractive index of the lower cladding layer. The second protection/barrier layer is optically transparent and designed with a refractive index less than, greater than, or the same as the refractive index of the core and approximately equal to the refractive index of the upper cladding layer.Type: ApplicationFiled: December 28, 2017Publication date: July 4, 2019Applicant: Lightwave Logic Inc.Inventors: Richard Becker, Michael Lebby, Youngwoo Yi

Publication number: 20190204507Abstract: One example includes an apparatus that includes a plurality of input/output (I/O) ports and a body portion. The plurality of I/O ports can be arranged at a plurality of peripheral surfaces of the body portion. The body portion includes a solid dielectric material having a substantially constant index of refraction. The body portion also includes parallel planar surfaces spaced apart by and bounded by the plurality of peripheral surfaces. The solid dielectric material in the body portion can be writable via a laser-writing process to form an optical waveguide extending between a set of the plurality of I/O ports.Type: ApplicationFiled: March 11, 2019Publication date: July 4, 2019Inventors: Raymond G.
