This python module implements the Luxtelligence LNOI400 PDK as components and technology specification for PhotonForge

Installation via pip:

pip install luxtelligence-lnoi400-forge

1. Download from PyPI the latest wheel file: luxtelligence_lnoi400_forge-*-py3-none-any.whl.

2. In the PhotonForge web interface, upload that file to load the LNOI400 PDK.

The simplest way to use the this PDK in PhotonForge is to set its technology as default:

import photonforge as pf
import luxtelligence_lnoi400_forge as lxt

tech = lxt.lnoi400()
pf.config.default_technology = tech

The lnoi400 function creates a parametric technology and accepts a number of parameters to fine-tune the technology.

PDK components are available in the component submodule. The list of components can be discovered by:

dir(lxt.component)

pdk_component = lxt.component.mmi1x2()

Utility functions cpw_spec and place_edge_couplers are also available for generating CPW port specifications and placing edge couplers at chip boudaries.

More information can be obtained in the documentation for each function:

help(lxt.lnoi400)

help(lxt.component.mmi1x2)

help(lxt.place_edge_couplers)

Please note that the 3D structures obtained by extrusion through this module's technologies are a best approximation of the intended fabricated structures, but the actual final dimensions may differ due to several fabrication-specific effects. In particular, doping profiles are represented with hard-boundary, homogeneous solids, but, in practice will present process-dependent variations with smooth boundaries.
