Title:
METHOD FOR PRODUCING NONLINEAR OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/024761
Kind Code:
A1
Abstract:
The present invention provides a method for producing a nonlinear optical device. A recessed part (10) is formed in the surface of a semiconductor substrate (100). The recessed part (10) is filled with a first liquid material (31) in a reduced pressure environment. A third liquid material (33) is prepared by bringing a second liquid material (32) into contact with the first liquid material (31) that fills the recessed part (10). A buried part (310) is formed by solidifying the third liquid material (33). The first liquid material (31) contains a first solute and a first solvent, or alternatively, is composed only of the first solvent. The second liquid material (32) contains a second solute and a second solvent. The second solute contains a nonlinear optical polymer. The concentration of the second solute in the second liquid material (32) is higher than the concentration of the first solute in the first liquid material (31).
