Abstract

Adiabatic polarization splitter-rotators are investigated exploiting continuous symmetry breaking thereby achieving significant device size and losses reduction in a single mask fabrication process for both SOI channel and ridge waveguides. A crosstalk lower than -25 dB is expected over 300nm bandwidth, making the device suitable for full grid CWDM and diplexer/triplexer FTTH applications at 1310, 1490 and 1550nm.

摘要

对绝热偏振分束器-旋转器进行了研究，利用连续对称性破缺，从而在用于SOI沟道和脊形波导的单次掩模制造工艺中实现了显著的器件尺寸减小和损耗降低。预计在300nm带宽上串扰低于-25dB，这使得该器件适用于1310nm、1490nm和1550nm的全栅格CWDM以及双工器/三工器FTTH应用。
