DESCRIPTION:Co-authors: Jason S. Pelc (Hewlett-Packard Laboratories)\, Ray
 mond G. Beausoleil (Hewlett-Packard Laboratories)\, Nikolas Tezak (Stanfor
 d University)\, Ryan Hamerly (Stanford University)\, Hideo Mabuchi (Stanfo
 rd University) \n\nThis talk will describe work at HP Labs to design and b
 uild photonic circuits on semiconductor platforms that use Kerr\, carrier-
 based and thermal nonlinearities to perform all-optical logic. We have dev
 eloped a semi-classical model to simulate quantum noise and spontaneous sw
 itching in circuits containing hundreds of components. With this model we 
 can address basic questions such as the minimum switching energy needed to
  avoid errors\, or whether the circuits have adequate digital signal resto
 ration. Recently\, we have been working to reduce the complexity and impro
 ve tolerance to fabrication variations in the circuit designs. I will also
  summarize our recent experimental efforts on all-optical logic devices.\n
