Iterative and efficient Bloch mode calculations for integrated photonics applications
Mohsen Kamandar Dezfouli,Daniele Melati,Yuri Grinberg,Muhammad Al-Digeil,Ross Cheriton,Pavel Cheben,Jens H. Schmid,Siegfried Janz,Da Xu +8 more
TL;DR: In this article , the authors show how existing iterative methods that were originally developed for resonant nanophotonic systems in the frequency domain can be reliably used for calculation of optical Bloch modes in complex wavevector domain.
Proceedings ArticleDOI
On-Chip Circular Optical Phased Arrays
TL;DR: In this article , a two-dimensional optical phased arrays with circular configurations was proposed to suppress grating sidelobes down to 10 dB, while enlarging the steering range to 0.24π and narrowing the angular beamwidths to 1.5°.
Proceedings ArticleDOI
Subwavelength Gratings for Silicon Photonic Integration
