The Photonically Optimized Embedded Microprocessors <ref> https://www.darpa.mil/program/photonically-optimized-embedded-microprocessors </ref> (''' POEM''') is [[DARPA]] program that addressed electrical communications link limitations by developing chip-scale and integrated photonic technology , enables seamless intrachip and offchip photonic communications that provide the required bandwidth with low energy/bit. "The POEM program will exploit wavelength division multiplexing (WDM), allowing much higher bandwidth capacity per link, which is imperative to meeting the communication needs of future microprocessors. Such a capability would propel the microprocessor onto a new performance trajectory and impact the actual runtime performance of DoD-relevant computing tasks for power-starved embedded applications and supercomputing" .For realizing POEM technology CMOS and DRAM-compatible photonic links should operate at high bit-rates with very low power dissipation. POEM should demonstrate photonic technologies that can be integrated within embedded microprocessors and enable seamless, energy-efficient, high-capacity communications within and between the microprocessor and DRAM.
