Patent number: 7484900Abstract: The present invention generally relates to an air cavity plastic package for a high frequency optical device. In one aspect, a module package for a high frequency optoelectronic device is provided. The module package includes an upper plastic housing having an upper cavity formed therein and a lower plastic housing having a lower cavity formed therein. The upper housing and the lower housing are configured to mate together such that the cavities form an enclosed air cavity between the housings. Additionally, upon creating a seal between the housings, an optical feed through is realized. The module package further includes a plurality of conductors disposed in the lower housing, each conductor having an upper end and a lower end, wherein the upper end is connectable to a chip disposed in the air cavity and the lower end is connectable to a board. In another aspect, a method of packaging and assembling a high frequency optical device is provided.Type: GrantFiled: October 5, 2006Date of Patent: February 3, 2009Assignee: Avanex CorporationInventors: Roberto Galeotti, Luigi Gobbi, Mario Bonazzoli

Patent number: 7228014Abstract: An electro-optical modulator is disclosed that has a microwave input, chip with a thin film resistor or a lumped resistor located between an input RF connector and an RF electrode on a Lithium Niobate chip. The accessory connection chip has a broadband attenuator like a thin film resistor which is placed in a microstrip line for effecting the electrical transmission to Lithium Niobate chip. The insertion of the thin film resistor before the RF electrode lowers the electrical return loss value as a function of frequency, allowing a lower driving voltage design or a reduced chip length without degrading the performances.Type: GrantFiled: March 11, 2004Date of Patent: June 5, 2007Assignee: Avanex CorporationInventors: Giovanni Gilardi, Paolo Milanese, Simone Pensa, Mario Bonazzoli, Luigi Gobbi

Patent number: 7062113Abstract: An integrated optical chip has a crystalline structure cut along parallel principal crystallographic planes and a thickness of less than 1.0 mm. An optical signal pathway is disposed generally longitudinally in one of the cut surfaces of the chip, and the chip is attached to a substrate material up to 1.0 mm thick and having similar coefficients of thermal expansion in that principal crystallographic plane. A grounding plane is disposed between the chip and substrate to provide an electrically conductive path between opposite lateral surfaces of the chip. A method of making the chip is also described.Type: GrantFiled: September 19, 2003Date of Patent: June 13, 2006Assignee: Corning IncorporatedInventors: Federico Caccavale, Luigi Gobbi, Marco Marazzi, Gloria Obetti
