DESCRIPTION:As photonic integrated circuits become more advanced with diffe
 rent multiplexing techniques\, the demand for sophisticated nanophotonic d
 evices increases. The conventional nanophotonic design method is showing l
 imitations with this trend. Firstly\, as the nanophotonic devices become m
 ore sophisticated\, only highly experienced photonic designers who have a 
 deep understanding of photonics can propose ideas to fulfill these demands
 . Secondly\, the sizes of conventionally designed devices tend to increase
  to meet the multifunctional requirements. Novel mathematical optimization
 -assisted methods are promising tools to significantly reduce the size of 
 silicon photonic components while maintaining their functionality and perf
 ormance. These methods have been investigated intensively over the past de
 cades. In this talk\, the conventional nanophotonic device design methods 
 are reviewed. The mathematical description of the nanophotonic device desi
 gn is given. Then\, the mathematical optimization-assisted design methods 
 are discussed\, including heuristic methods and the adjoint method. Finall
 y\, the possible future directions of mathematical optimization-assisted m
 ethods will be discussed\, including potential limitations and problems th
 at still need to be solved.\n\nSpeaker(s): Guowu Zhang\, \n\nRoom: TR0070\

X-ALT-DESC:Description: <br /><p>As photonic integrated circuits become mor
 e advanced with different multiplexing techniques\, the demand for sophist
 icated nanophotonic devices increases. The conventional nanophotonic desig
 n method is showing limitations with this trend. Firstly\, as the nanophot
 onic devices become more sophisticated\, only highly experienced photonic 
 designers who have a deep understanding of photonics can propose ideas to 
 fulfill these demands. Secondly\, the sizes of conventionally designed dev
 ices tend to increase to meet the multifunctional requirements. Novel math
 ematical optimization-assisted methods are promising tools to significantl
 y reduce the size of silicon photonic components while maintaining their f
 unctionality and performance. These methods have been investigated intensi
 vely over the past decades. In this talk\, the conventional nanophotonic d
 evice design methods are reviewed. The mathematical description of the nan
 ophotonic device design is given. Then\, the mathematical optimization-ass
 isted design methods are discussed\, including heuristic methods and the a
 djoint method. Finally\, the possible future directions of mathematical op
 timization-assisted methods will be discussed\, including potential limita
 tions and problems that still need to be solved.</p>
