I sent this paper earlier today to a subgroup of most relevant people, but I think it may be of interest for the whole group. Semion -- ******************************************** Semion K.

[Aspuru-Guzik group list] FW: [Seas-faculty] [Ee-seminars] Reminder- Electrical Engineering Seminar Friday 11/1

Shayan Mookherjea University of California, San Diego A chip technology based on silicon is poised to replace crystals such as lithium niobate, and KTP for nonlinear optics at infrared wavelengths, while adding the benefits of CMOS electronic compatibility, scalability and manufacturability. And, while silicon is a poor classical laser material, it can be an excellent quantum light source. In this talk, I will describe how the emerging trend of using silicon foundries is changing the nature of exploratory research in photonics. Whereas today’s commercial silicon photonic devices focus mainly on one metric (joules per bit in communication links), research needs are more diverse, and some believe that silicon photonics foundry-built devices must sacrifice performance in exchange for low-cost, large-volume manufacturing. In our work, we often combine certain types of foundry manufacturing with device designs which recognize the plusses and minuses of this approach, and have been able to demonstrate record performance in different types of devices (typical size 0.01 mm^2 in each case): i) Filter with 100 dB on-off contrast and less than 3 dB insertion loss, and 10x tunable bandwidth (electrical control) ii) Four-wave mixing with only 2.5 mW pump power, and its use for wavelength conversion in an optically-interconnected packet-switched data center iii) The first heralded single-photon source from silicon. This chip-scale device operates at room temperature; we have now made it electrically tunable and emit a comb of wavelengths. To explain these, I will also summarize our research on fat-pipe optical switching, coupled microring resonators, infrared camera imaging, light transport statistics, nano-oxidation, and Anderson localization.
