+--- Simple MZI, tested using Facet-Attached Micro Lenses (FaML) ---
+  
+by Lukas Chrostowski, 2024
+   
+Example simple script to
+ - choose the fabrication technology provided by Applied Nanotools,  using silicon nitride (SiN) waveguides
+ - use the SiEPIC-EBeam-PDK technology
+ - using KLayout and SiEPIC-Tools, with function including connect_pins_with_waveguide and connect_cell
+ - create a new layout with a top cell, limited a design area of 1000 microns wide by 410 microns high.
+ - create one Mach-Zehnder Interferometer (MZI) circuit with a small path length difference
+ - export to OASIS for submission to fabrication
+ - display the layout in KLayout using KLive
+ 
+ Test plan
+ - count lenses from the top (top is 1)
+ - laser input on top lens (1), detector on second (2) 
+
+Use instructions:
+
+Run in Python, e.g., VSCode
+
+pip install required packages:
+ - klayout, SiEPIC, siepic_ebeam_pdk, numpy
