  • Publication number: 20050013330
    Abstract: A method of tuning optical components integrated on a monolithic chip, such as an optical transmitter photonic integrated circuit (TxPIC), is disclosed where a group of first optical components are each fabricated to have an operating wavelength approximating a wavelength on a standardized or predetermined wavelength grid and are each included with a local wavelength tuning component also integrated in the chip. Each of the first optical components is wavelength tuned through their local wavelength tuning component to achieve a closer wavelength response that approximates their wavelength on the wavelength grid.

  • Patent number: 6603093
    Abstract: A method for aligning optical components includes positioning a flexure having an attached first optical component with respect to a substrate having a second optical component attached thereto. The flexure has at least two legs, and each leg has a foot portion. The method further includes coupling at least one leg of the two legs to the substrate at a point of contact between the foot portion of the at least one leg and the substrate. The method further includes adjusting the alignment of the optical components by spot welding a location on the leg. Spot welding on the substrate may also be used to adjust the alignment of the optical components.

  • Patent number: 6585427
    Abstract: A flexure and package including the same are provided. In one embodiment, the flexure is coupled to a second optical element and a substrate to maintain the second optical element in alignment with a first optical element. The flexure comprises a body, a pair of front and back legs. The attachment of the rear legs to the substrate causes the flexure to move from a first flexure position to a second flexure position, the distance between the first flexure position and the second flexure position equaling an offset distance. A specified length of the body is chosen such that the offset distance causes a second offset distance of the second optical component held by the flexure, and this second offset distance is within a specified range. The second offset distance is equal to the difference between a primary second optical component position and a secondary second optical component position.

  • Publication number: 20030095736
    Abstract: A monolithic transmitter photonic integrated circuit (TxPIC) chip comprises an array of modulated sources formed on the PIC chip and having different operating wavelengths according to a standardized wavelength grid and providing signal outputs of different wavelengths. Pluralities of wavelength tuning elements are integrated on the chip, one associated with each of the modulated sources. An optical combiner is formed on the PIC chip and the signal outputs of the modulated sources are optically coupled to one or more inputs of the optical combiner and provided as a combined channel signal output from the combiner. The wavelength tuning elements provide for tuning the operating wavelength of the respective modulated sources to be approximate or to be chirped to the standardized wavelength grid. The wavelength tuning elements are temperature changing elements, current and voltage changing elements or bandgap changing elements.

  • Patent number: 5875053
    Abstract: Several embodiments are described for induced electric field or E-field poling of QPM nonlinear crystal materials, such as LiNbO.sub.3, LiTaO.sub.3 and KTP, utilizing approaches which, for the most part, avoid the necessity of depositing or otherwise forming a series of spatially disposed conductive electrodes on one surface of the nonlinear crystal material. E-field poling is accomplished by applying a high voltage electric field in excess, for example, in the range of several kilovolts per cm to several 100 kilovolts per centimeter, at room temperature to provide inverted domains in a pattern of continuously alternating domains corresponding to the regions formed on the first z surface of the crystal. The employment of single, planar-applied liquid electrodes is preferred eliminating any necessity of forming and removing previously formed metal electrodes in the poling process.

  • Patent number: 5170460
    Abstract: A waveguide in optically nonlinear materials for quasi-phase-matched frequency conversion of electromagnetic waves, arranged in a crystal substrate. The waveguide includes a periodically alternating crystal orientation necessary for quasi-phase-matching. The crystal orientation is provided in the form of a periodically domain inverted structure of ferroelectric domains, with reversed crystal orientation in relation to intermediate regions located between the domains. The domain structure is achieved by use of a periodic mask structure applied to the surface of the substrate in combination with a subsequent heat treatment of the substrate.
