Proposal for an ultracompact polarization-beam splitter based on a photonic-crystal-assisted multimode interference coupler
2007 (English)In: IEEE Photonics Technology Letters, ISSN 1041-1135, E-ISSN 1941-0174, Vol. 19, no 9-12, 825-827 p.Article in journal (Refereed) Published
An ultracompact polarization-beam splitter (PBS) combining a multimode interference (MMI) coupler and some photonic crystal (PC) structures is presented. The MMI coupler is designed to collect polarized powers reflected by or transmitted through an internal PC sturcture. The simulation result shows that the designed PBS is very short (about 50 mu m), and has a low insertion loss, a high extinction ratio, and a broad bandwidth.
