Polarization splitter-rotator on thin film lithium niobate based on multimode interference.

Polarization splitter-rotators (PSRs) are the key elements to realize on-chip polarization manipulation. Current PSRs on thin film lithium niobate (TFLN) rely on sub-micron gaps to realize mode separation, which increases the difficulties of lithography and etching. In this paper, a PSR on TFLN based on multimode interference (MMI) is demonstrated.

[Analysis on quantitative trait loci associated with leaf chlorophyll content and their interactions with environment at late growth stage of rice].

By using a population of 123 F12 lines (recombinant inbred lines, RILs) derived from a cross between India variety Dular and Japanica variety Lemont, an analysis of quantitative trait loci (QTL) was conducted for the flag leaf chlorophyll content of rice. The chlorophyll content was determined by SPAD-502 in 2005 and 2006, respectively, and software QTLMapper 1.6 was applied to analyze the QTL, including the additive and epistatic effects and the QTL interactions with environment for chlorophyll content.
