Patent number: 8373996Abstract: Consistent with an aspect of the present disclosure, a package is provided that has a carrier and first and second substrates provided on the carrier. Conductive traces are provided on the first substrate (upper traces) and below it (lower traces) to provide two levels of electrical connectivity to a photonic integrated circuit (PIC) provided on the second substrate. As a result, an increased number of connections can be made to the PIC in a relatively small package, while maintaining adequate spacing and line widths for each trace. In addition, the lower traces are connected to bonding pads on the surface of the first substrate and are thus provided in the same plane as the upper traces. Testing of and access to both upper and lower traces is thus simplified.Type: GrantFiled: July 7, 2009Date of Patent: February 12, 2013Assignee: Infinera CorporationInventors: Donald J. Pavinski, Jr., August Spannagel, Charles H. Joyner, Peter W. Evans, Matthew Fisher, Mark J. Missey

Patent number: 8155531Abstract: Photonic integrated circuits (PICs) may include transmit and receive PICs that include individually tunable optical elements. In one implementation, a device may include a number of optical elements that form a number of optical channels. Tuners may be used to modify a property associated with the at least one of the optical elements where the modified properties of the optical elements adjust a frequency grid of the optical channels.Type: GrantFiled: May 18, 2009Date of Patent: April 10, 2012Assignee: Infinera CorporationInventors: Sanjeev Murthy, Mark J.

Patent number: 7747114Abstract: A monolithic optical transmitter photonic integrated circuit (TxPIC) comprises a plurality of integrated modulated sources which, when all operated at constant current, display a power output that varies as a function of array position similar to a quadratic-shaped curve and, further, forming an array of signal channels each having a different wavelength output. An optical combiner/decombiner is integrated in the circuit and has at least one free space region with a plurality of ordered bands along its edge where the zero order band is substantially at a longitudinal centerline of the free space region and where, on either side of this band, is a first order band followed by additional higher order bands.Type: GrantFiled: September 29, 2008Date of Patent: June 29, 2010Assignee: Infinera CorporationInventors: Frank H.

Patent number: 7529436Abstract: A photonic integrated circuit that includes a plurality of active and passive components on a substrate where one of the components is an optical combiner/decombiner having at least one free space coupler region and a plurality of longitudinal ridge waveguides each extending in the circuit from a first region of the waveguide and coupled at a second region of the waveguide at the free space coupler region.
