Ring filter#
Calculations#
For a ring resonator we need to define:
Optical parameters:
coupling coefficient: will define resonance extinction ratio for a particular ring loss.
Free spectral range.
Electrical parameters:
VpiL
Resistance

Layout#
gdsfactory easily enables you to layout Component with as many levels of hierarchy as you need.
A Component is a canvas where we can add polygons, references to other components or ports.
Lets add two references in a component.

Top reticle assembly#
Once you have your components and circuits defined, you can add them into a top reticle Component for fabrication.
You need to consider:
what design variations do you want to include in the mask? You need to define your Design Of Experiment or DOE
obey DRC (Design rule checking) foundry rules for manufacturability. Foundry usually provides those rules for each layer (min width, min space, min density, max density)
make sure you will be able to test te devices after fabrication. Obey DFT (design for testing) rules. For example, if your test setup works only for fiber array, what is the fiber array spacing (127 or 250um?)
if you plan to package your device, make sure you follow your packaging guidelines from your packaging house (min pad size, min pad pitch, max number of rows for wire bonding …)

As you can see there are 6 devices with optical and electrical ports.
You can turn each label into a test manifest CSV file to interface with your lab instrumentation functions.
Each measurement will use a different measurement procedure and settings measurement_settings
The default measurement settings for each functions can also be defined in a separate CSV file and easily editable with Excel or LibreOffice.
