v0.3.54

• Added automated waveguide crossing
• Documentation buttons added to PCells: contra-directional coupler, taper
• Added Dream Photonics 1x2 splitter

v0.3.53

• Compact model files moved to the Technology folder / CML
• Integration with OPICS
• Single source CML can be read by Lumerical and OPICS
• Contra Directional Coupler simulation

v0.3.52

• SiN component library for 895 nm wavelength
• opics circuit simulator support for selection of "EBeam" library components

v0.3.51

• wg_heater PCell, with compact model. Compact model only valid for Si strip 0.5 µm width at 1550 nm wavelength.
• Waveguide_bump improvement: user specifies target ∆L, and the PCell solves for the geometry
• XSection, added SiN and wafer

v0.3.50

• 'Waveguide' is now a virtual layer, not fabricated. 'Si' for fabrication.

v0.3.48

• SiN waveguide and model
• SiN Y branch
• SiN waveguide heater
• Si thermally tuned ring resonator
• 1310 nm compound waveguide
• "Waveguide" layer used to draw a Path for the Si and SiN waveguides

v0.3.47

• putting Lumerical CML file in the PDK

v0.3.46

• removed the layer 31_Si_p6nm , and fixing the Beta library layer

v0.3.45

• renaming the PDK folder to be "klayout/EBeam" rather than "klayout_dot_config/tech/EBeam"
• added silicon nitride SiN layer (1/5) and a SiN library
• thermo-optic example layout
• some additional documentation
• bug fixes on a few PCells

v0.3.44

Minor fixes:

• ebeam_taper_te1550: asymmetry of the design
• contradirectional coupler
• ebeam_dc_te1550

Changes:

• design for test: both TE and TM facing the same direction
• updated process control monitoring

Addition:

• Addition of black box grating coupler models in the Lumerical CML (1310 and 1550, TE and TM)
