Abstract : We describe a program which endeavors to make significant progress towards the realization of very high density, fast, InP-based optoelectronic spatial light modulators (SLMs). The central concept of the devices is to eliminate as many contacts to the SLM as possible by supplying integral, local circuit power and control via the connection of the active circuit to integrated photovoltaic (PV) cells. Power to the circuits is thereby supplied by a bright light source operating at a different wavelength than the optical data channel. The SLM will be fabricated in InP-based materials due to the ease of integration of photovoltaic cells (used in providing circuit power and control), with high bandwidth transceiver optoelectronic integrated circuits (OEICs). Work includes materials and device fabrication, packaging and systems demonstrations. In addition to applications in optical interconnection and optical computing, such contactless circuit concepts can also be applied to many diverse systems such as for providing highly synchronous optical clock signals on VLSI chips, and for powering OEICs placed at the end of remote probes where size, power, and environmental restrictions prohibit the placement of the power source adjacent to the active electronics. We are engaged in a broad program directed at investigating the fundamental limits confronting materials, devices, circuits and systems which make use of the family of novel devices which are based on the optical powering concept.
