An analytical model for mid-infrared (mid-IR) silicon Raman lasers (SRLs) is developed. The relative intensity noise (RIN) transfer from the pump to the Stokes in the lasers is also investigated. The analytical model can be used as a versatile and efficient tool for analysis, design and optimization of mid-IR SRLs. It is shown that conversion efficiency of 70% is attainable and the low-frequenc...

A significant research base has increasingly substantiated that teachers are among the most significant players affecting student achievement in second language classrooms. As a result, teacher-related variables have enjoyed much research attention over the recent decades in both mainstream education and English Language Teaching (ELT).
