Abstract : This report describes the results of Honeywell's effort under the Optoelectronic Technology Consortium project. The program involved a consortium of Honeywell, AT&T, IBM and Martin Marietta. The overall goal of the program was to develop parallel fiber optic data link component and packaging technology and to demonstrate a link possessing 32 channels, each operating a 500 Mbps for an aggregate data rate of 16 Gbps. Baseline and alternate technologies were investigated. Honeywell's effort included: (1) the development of AlGaAs waveguide based four element electro-optic modulator arrays as an alternate transmitter technology, (2) packaging technology required to couple single mode fiber to, and multimode fiber from, the modulator array, and (3) a polymer waveguide based board level interconnect demonstration included an expanded beam connector feasibility study. Partway through the program we added a task to develop a second source capability for the Vertical Cavity Surface Emitting laser (VCSEL) arrays. During the program we demonstrated multi-gigahertz bandwidth modulator arrays with a contrast ratio >10dB, and a voltage-length product of approximately 5.5V- cm. The packaging technique developed allowed one to maintain a 1 dB additional coupling loss over the 0 to +123 deg C temperature range. The polymer waveguide demonstration showed that 60 optical waveguide channels could be coupled from board to-board through a 3rnm connector with a fraction of a millimeter board to board alignment tolerance. We also demonstrated the fabrication of VCSEL arrays using MOCVD as the epitaxial layer growth technology.
