ABSTRACT:
The present invention discloses a method for fabricating polymer wavelength filter with high-resolution periodical structure, which comprises: a positive photo-resister film is coated or a substrate, holographically exposed with grating pattern, and coated with a negative photo-resister film, then exposed by UV light and developed to obtain a waveguide mold having negative waveguide; a PDMS film coated on the waveguide mold, baked and peeled off to obtain a PDMS mold; a first tunnel formed over the PDMS mold, injected with a first UV polymer, then cured and separated the first UV polymer having groove to be the cladding layer of the polymer wavelength filter; a second UV polymer injected into the groove of the cladding layer, and cured to form the core of the waveguide in the groove of the cladding layer to finally be the polymer wavelength filter.
