Abstract
The next generation giga-Hertz microprocessors require a high-speed clocking scheme with a robust and low-skew clock distribution network. The guided-wave optoelectronic clock distribution networks on multichip modules (MCMs) is believed to satisfy the high-speed clocking requirements by providing superior network bandwidth, low power consumption,and large fanout compared to the electrical interconnect counterpart. In this paper, we report a sixteen-fanout H-tree clock distribution network on MCMs, which utilizes silica glass waveguides and micromachined silicon microstructures. The proposed optoelectronic multichip modules (OE-MCMs) can be fabricated in a CMOS compatible batch process without modifying the conventional IC fabrication facilities and the OE-MCM assembly/packaging processes are simple and economical due to the arrays are characterized at wavelengths of 1310 nm and 1550 nm. The issues of system-level modeling and prototyping are also addressed by discussing VHDL/FD-BPM-based simulation tool: Optoelectronic System Simulator, such that OE-MCMs can be rapidly-designed and mass-produced through the design automation tools.
