luxtelligence-ltoi300-forge 2.1.0

Luxtelligence LTOI300 PDK implementation for PhotonForge

Luxtelligence LTOI300

This python module implements the Luxtelligence LTOI300 PDK as components and technology specification for PhotonForge

For LTOI300 design rules, design manual and PDK specifications, please contact Luxtelligence.

Installation

Installation via pip:

pip install luxtelligence-ltoi300-forge

Usage

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

import photonforge as pf
import luxtelligence_ltoi300_forge as lxt

tech = lxt.ltoi300()
pf.config.default_technology = tech

The ltoi300 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)

print(lxt.component_names)

pdk_component = lxt.component.mmi1x2_oband()

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

help(lxt.ltoi300)

help(lxt.component.mmi1x2_oband)

Finally, an extrusion demo for the technology can be seen by running:

lxt.plot_cross_section()

Warnings

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.
