µ-NLO: versatile µ-imprinting process of second order non linear optical properties in glasses
Technology Additive manufacturing
This versatile µ-imprinting process of second order Non Linear Optical (NLO) properties in glasses will find applications in :
- Photonic integrated circuit (PIC)
- Electro optic components
- χ(2) Nonlinearity Conversion
Our technology is an imprinting method allowing to structure, at multiple scales, the second order non linear (SONL) optical properties of amorphous materials.
The optical elements are formed directly on a wide variety of vitreous compositions and are capable of Second Harmonic Generation (SHG).
Micrometric localization of the electro-optical anisotropy / Periodical and long range χ(2) structuring : a SONL grating
- Large variety of micrometric structures (dots, squares, lines…), on demand.
- Long range χ(2) structuring (cm²).
- Large variety of glasses.
