Polymer Integrated Photonics Circuits

  • High electro-optic efficiency: Organic materials exhibit large electro-optic coefficients, enabling low-voltage, high-speed modulation in photonic circuits.
  • Tunable optical and emission properties: Their molecular structures can be engineered to control refractive index, nonlinear response, and light emission for lasers or amplifiers.
  • Low-cost and versatile fabrication: Solution-based processing methods allow easy, low-temperature, and scalable manufacturing on various substrates.
  • Broad transparency and ultrafast response: Many organics are transparent across visible to near-infrared ranges and support femtosecond-level optical responses.
  • Lightweight and flexible integration: Their mechanical flexibility and compatibility with hybrid platforms enable compact, energy-efficient, and adaptable photonic devices.
