Can some one post a layout file for: RZ9chTX/  
1) dual-fiber collimator, one for input and one for output, with 8 degree angled surface; pTcN8E&Unz  
2) a 8 degree angled GRIN lens (NSG SLW180) ^' b[#DG>F  
3) a mirror d/I*$UC  
*46hw(L  
Adjust the layout file, thus the output beam return back to the output fiber. c ^+{YH;k  
\yo)oIi[p  
The fiber can be SMF-28 corning fiber. $-BM`Zt0;  
^14a[ta/'  
This is a very often used dual-fiber collimation for Telecom fiber optics. Quite a few example use this configuration, such as tilting mirror type VOAs. }woNI
