On-chip creation of novel wavelengths in mass-manufacturable waveguides

Creating novel wavelengths on a photonic chip has many application possibilities in various domains ranging from data- and telecommunications to on-chip spectroscopy and biosensing. An often used process for creating new wavelengths is nonlinear wavelength conversion in on-chip waveguides. To ensure sufficient optical power conversion towards the new wavelength, a commonly used strategy is to use rather exotic waveguide dimensions to make the wavelength conversion process efficient. Such exotic waveguide dimensions, however, do not allow mass-fabrication of the photonic chips in large-scale foundries.

Solution

Therefore, the Brussels Photonics Team (B-PHOT) has developed an alternative approach for designing on-chip waveguides allowing efficient wavelength conversion while complying with the standard waveguide fabrication rules of photonic chip foundries.

Competitive advantages

  • Efficient wavelength conversion in compact waveguides on a photonic chip
  • Wavelength conversion in mass-manufacturable photonic chips
