SPARK PHOTONICS COMPONENT LIBRARY

Spark Photonics logo

The Spark Photonics (SP) Component Library focuses on operating wavelengths in the 700-1300 nm range (I/Z/Y/J bands). In addition to the passive component cells, several parameterized cells (PCells) are included to assist with layout generation.

Parameterized cells (PCells) for easier layout generation

  • 1x2 MMI

  • 2x2 MMI

  • 1x4 MMI

  • Taper

  • Grating coupler

  • Ring resonator

  • Spiral (circular and rectangular)

The following are planned for future library releases

  • Additional validated cells, including:

    • Waveguide crossings and terminations

    • Grating couplers

    • Directional couplers (90/10, 99/1)

    • Polarization rotators

    • Additional MMIs (1x3, 1x4, 1x7, 1x8)

    • Arrayed waveguide gratings

    • Thermal phase shifters

  • Hardware validation and further refinement of library components

  • Extension of library to visible wavelengths and O/C/L bands in SiN

  • Statistical variation in models

Passive Components Quantity Current Performance
Waveguides (straight, 90-degree bend, S-bend) 12 Propagation loss:
• 0.5-2.5 dB/cm (700-1000 nm)
• 0.2-0.5 dB/cm (1000-1300 nm)
3 dB Y-branch 4 Loss <0.25 dB per component
1x2 MMI 14 varies by component and polarization
2x2 MMI 14 varies by component and polarization
Layer transition 2 Loss <0.1 dB in TE, <0.6 dB in TM
Edge coupler 4 Varies by fiber type

Other helpful information to know

  • The current PDK version that should be used for passive or active MPW runs is 5.5 or newer. Please contact us to confirm if an older version will be compatible.

  • The community of organizations who use our PDK is growing. To support this design work and provide information about common questions, we’ve set up help desk functions. See details about getting an account.
