A Mechanical-Optical Interface for 25+ Gbps VCSEL/PD Fiber Coupling, January 2017

Abstract: As parallel optics data rates transition from 10 Gbps to 25 Gbps and beyond, VCSELs and photodiodes (PDs) are evolving to support the higher transmission rates. In order to maintain system performance as speeds increase and tolerances become tighter, an improved method is needed to efficiently couple VCSEL/PD array optical outputs to fiber optic networks. The mechanical-optical interface (MOI) is a monolithic component with an array of collimating lenses designed for efficient coupling between the on-board active components and a detachable fiber optic connector. © 2017 Society of Photo Optical Instrumentation Engineers.

Performance Methodology and Characterization of a Multi-Fiber Expanded Beam Lensed Optical Interconnect, April 2016

Abstract: The demand for high performance, cost-effective optical interconnects is driving the need for novel connectors in the optical communication industry. A multi-fiber lensed ferrule has been introduced that addresses backplane and ganged application requirements through the use of molded, expanded beam optics. The new ferrule maintains the same footprint as traditional multi-fiber ferrules, but uses an array of lenses on the front face to expand and collimate up to sixty-four channels simultaneously. The monolithic ferrule uses a hermaphroditic post and hole mating system to eliminate the costs associated with traditional steel alignment pins. The final result is a collimated beam connector system that enables debris insensitive connections for standard multi-mode optical fiber. © 2016 IEEE. Personal use of this material is permitted.

Development and Qualification of a Mechanical Optical Interface for Parallel Optics Links, February 2015

Abstract: As parallel optics applications continue to expand, there remains a need for an effective coupling interface between the board-level active components and the passive components of the network. While mid-board level photonic turn connectors are available, coupling interfaces are generally not available outside of proprietary solutions. Development of a general mechanical-optical coupling interface opens the door for broader parallel optics implementation. © 2015 Society of Photo Optical Instrumentation Engineers.

Theoretical and Empirical Qualification of a Mechanical Optical Interface for Parallel Optics Links, February 2015

Abstract: As the implementation of parallel optics continues to evolve, development of a universal coupling interface between VCSEL/PD arrays and the corresponding photonic turn connector is necessary. A newly developed monolithic mechanical-optical interface efficiently couples optical transmit/receive arrays to the accompanying fiber optic connector. This paper describes the optical model behind the coupling interface and validates the model using empirical measurements. © 2015 Society of Photo Optical Instrumentation Engineers.
