Packaging of opto-electronic components - as opposed to semiconductor or electronics ICs - requires not only hermeticity but also proper alignment of optical elements. Due to tolerances in the range of a few microns at best, conventional technology usually requires laborious active alignment steps to couple light efficiently into the fiber. A simple optical coupling and alignment scheme is presented which enables the fabrication of cost effective 10 Gbit/s TOSA (transmitter optical sub-assembly) modules which are based on edge-emitting laser diodes packaged hermetically in micro-machined silicon structures.

The EPON (Ethernet passive optical network) standard (IEEE 802.3ah) only covers physical and data link layers; the rest is considered out-of-scope. This article explores several interesting research problems brought forward by the EPON architecture, but left out by the standard.

We demonstrate for the first time a 10-user, truly-asynchronous, gigabit OCDMA experiment over 50 km transmission using 511-chip SSFBG encoder/decoder and supercontinuum-based optical thresholder. Suppression of both beat noise and MAI are keys to the success.
