Abstract
A parallel optics and wavelength division multiplexing package for multiplexing optical data signals for transmission, or for receiving and demultiplexing optical data signals. The package includes an array of diodes mounted on a parallel transmitter or receiver circuit for receiving electrical signals from the circuit and converting them into an array of corresponding light signals, or for receiving an array of light signals and converting them into an array of corresponding electrical signals. In a transmitter package, an optical multiplexer, located adjacent the array of diodes, receives the array of light signals and converts them into a set of corresponding parallel multiplexed light signals. In a receiver package, an optical demultiplexer, located adjacent the array of diodes, receives a set of parallel multiplexed light signals and converts them into the array of demultiplexed light signals. A lid mounted on the optical multiplexer or demultiplexer includes alignment pins for aligning the multiplexer or demultiplexer with a parallel fiber ribbon for transmitting or receiving the light signals. The package can include an hermetic or non-hermetic enclosure, depending upon the …
