โฆ Synopsis
In this letter, we report a new architecture for clock and broadcast distribution using optical interconnect components, such as vertical cavity surface emitting lasers (VCSEL) and pin photodiodes with benefits of diffractive optical elements (DOE) fan-out. A two-bit-large bus for broadcast or clock distribution demonstration is presented using collective wiring technologies and MCM hybridization process in a standard BGA package. Diffractive optical elements allow one to four distribution scene through an optical plate. Specific laser drivers for VCSELs and photodiode receiver are realized in complete CMOS 0.6 mm transmitter and receiver chips.

An all-optical packet รฟltering module for WDM broadcast-and-select star networks is introduced. At each time instant, only one packet per wavelength is allowed to pass to the star coupler. Therefore, collisions are avoided and the network performance is improved. The proposed module is based on the
