In some other embodiments, color filters are between a waveguide and outcoupling elements. The color filters limit the wavelengths of light that interact with and are outcoupled by the outcoupling elements. In yet other embodiments, a different waveguide is provided for each range of wavelengths to be outputted. Incoupling optical elements selectively incouple light of the appropriate range of wavelengths into a corresponding waveguide, from which the light is outcoupled.

  • Patent number: 10983277
    Abstract: An optical subassembly includes a planar dielectric waveguide structure that is deposited at temperatures below 400 C. The waveguide provides low film stress and low optical signal loss. Optical and electrical devices mounted onto the subassembly are aligned to planar optical waveguides using alignment marks and stops. Optical signals are delivered to the submount assembly via optical fibers. The dielectric stack structure used to fabricate the waveguide provides cavity walls that produce a cavity, within which optical, optoelectronic, and electronic devices can be mounted. The dielectric stack is deposited on an interconnect layer on a substrate, and the intermetal dielectric can contain thermally conductive dielectric layers to provide pathways for heat dissipation from heat generating optoelectronic devices such as lasers.

  • Patent number: 10983273
    Abstract: The optical phased array may use a grating based emitter in order to emit light out of the plane of a PIC chip from an array of output waveguides. A longer grating allows for a larger aperture in the output waveguide dimension and allows for a small spot size. However, even for the relatively thick grating layers available in production foundries, the gratings still cause light to decay within less than 0.5 mm. To reduce the grating strength, some or all of the diffraction gratings may only be provided between the output waveguides, e.g. over trenches between the output waveguides, but not over top the output waveguides, whereby the periodicity only interacts with the weaker evanescent tails of the confined mode instead of the entire cross section of the output waveguides. By forming sufficiently narrow slots in the grating layer only down to the upper cladding layer, the diffraction gratings may be made extremely weak.

  • Patent number: 9618709
    Abstract: A technique for fabricating a hybrid optical source is described. During this fabrication technique, a III-V compound-semiconductor active gain medium is integrated with a silicon-on-insulator (SOI) chip (or wafer) using edge coupling to form a co-planar hybrid optical source. Using a backside etch-assisted cleaving technique, and a temporary transparent substrate with alignment markers, a III-V compound-semiconductor chip with proper edge polish and coating can be integrated with a processed SOI chip (or wafer) with accurate alignment. This fabrication technique may significantly reduce the alignment complexity when fabricating the hybrid optical source, and may enable wafer-scale integration.

  • Patent number: 9470844
    Abstract: A low loss high extinction ratio on-chip polarizer has at bi-layer optical taper with an input port of width W1 that communicates with a mode squeezer, followed by an S-bend (or dump bend), and finally a taper having an output port of width W1. The illumination that passes through the low loss high extinction ratio on-chip polarizer has a TM0 mode converted to a TE1 mode which is lost in the mode squeezer and S-bend section, while an input TE0 mode is delivered at the output as a substantially pure TE0 signal of nearly undiminished intensity.

  • Patent number: 9455299
    Abstract: Non-silicon based semiconductor devices are integrated into silicon fabrication processes by using aspect-ratio-trapping materials. Non-silicon light-sensing devices in a least a portion of a crystalline material can output electrons generated by light absorption therein. Exemplary light-sensing devices can have relatively large micron dimensions. As an exemplary application, complementary-metal-oxide-semiconductor photodetectors are formed on a silicon substrate by incorporating an aspect-ratio-trapping technique.

  • Patent number: 9366822
    Abstract: A photonic resonator system is designed to use thermal tuning to adjust the resonant wavelength of each resonator in the system, with a separate tuning circuit associated with each resonator so that individual adjustments may be made. The common electrical ground connection between the tuning circuits is particularly formed to provide thermal isolation between adjacent resonators by including a capacitor along each return path to ground, where the presence of the capacitor's dielectric material provides the thermal isolation. The use of capacitively coupling necessarily requires the use of an AC current as an input to the heater element (conductor/resistor) of each resonator, where the RMS value of the AC signal is indicative of the amount of heat that is generated along the element and the degree of wavelength tuning that is obtained.

  • Patent number: 9261647
    Abstract: Quasi-phase matched (QPM), semiconductor photonic waveguides include periodically-poled alternating first and second sections. The first sections exhibit a high degree of optical coupling (abbreviated “X2”), while the second sections have a low X2. The alternating first and second sections may comprise high-strain and low-strain sections made of different material states (such as crystalline and amorphous material states) that exhibit high and low X2 properties when formed on a particular substrate, and/or strained corrugated sections of different widths. The QPM semiconductor waveguides may be implemented as silicon-on-insulator (SOI), or germanium-on-silicon structures compatible with standard CMOS processes, or as silicon-on-sapphire (SOS) structures.

One method comprises forming a resist over a pool of acidic or basic material on a substrate structure, selectively exposing the resist to an energy source to form exposed resist portions and non-exposed resist portions, and diffusing acid or base of the acidic or basic material from the pool into proximal portions of the resist. Another method comprises forming a plurality of recesses in a substrate structure. The plurality of recesses are filled with a pool material comprising acid or base. A resist is formed over the pool material and the substrate structure and acid or base is diffused into adjacent portions of the resist. The resist is patterned to form openings in the resist.
