“High Index Contrast Silicon-On-Insulator Photonics: From Practical Limitations to New Opportunities” - Professor Shayan Mookherjea
Monday, July 27, 2009 2:00 PM to 3:30 PM CREOL 102
Abstract:
I will discuss my group’s recent work on silicon photonics for novel and upcoming applications in on-chip photonics. Part of the talk will discuss the novelty and future prospects for silicon photonics applications and research from a university researcher’s perspective, who occasionally works with industrial partners in this work.
High-index contrast structures, such as silicon on insulator (SOI) waveguides and couplers are not amenable to the well-developed and insightful tools of our field, such as coupled mode theory, paraxial propagation, etc. Brute-force numerical simulations cannot handle large-scale integrated structures, which may consist of a hundred or more individual elements. Analytical tools must be augmented, often using numerical or quasi-numerical methods, while attempting to retain physical insight.
Practically, disorder inevitably arises from the limitations of lithography or self-assembly. Disorder effects are much more severe for high index contrast, sub micron scale devices, such as SOI photonics, than in any previous generation of integrated optics. Consequently, some proposed applications, such as slow light, are severely impacted. On the other hand, SOI photonics can also reveal interesting new physics, such as light localization, which may offer new approaches to achieve desired functionality in spite of challenging fabrication and design requirements.
