Challenges in the Market

• Fabrication Complexity and Material Uniformity Issues
  Nanophotonic OPOs demand precise control of waveguide geometry and nonlinear material uniformity at the nanoscale. Minor fabrication defects can shift phase-matching conditions, affecting performance. High-precision lithography and etching increase costs and limit throughput. As production scales, maintaining consistency across wafers remains a major technical and economic hurdle for manufacturers.

• Thermal Instability and Power Handling Limitations
  Nanophotonic devices face thermal management challenges due to dense optical confinement and limited heat dissipation. Power-induced refractive index changes can destabilize oscillation conditions, affecting spectral output. Although material engineering and advanced cooling designs mitigate these issues, thermal drift continues to impact system stability, especially in continuous-wave operations.

• Limited Output Power Compared to Bulk Systems
  Despite efficiency gains, chip-scale OPOs typically produce lower output powers than bulk or fiber OPOs. Scaling output without sacrificing beam quality or damaging nanoscale structures is challenging. While arrays and resonator coupling strategies are emerging, achieving watt-level power on-chip remains difficult. This limits adoption in applications requiring high optical intensities.
