Abstract

The present invention provides certain polymeric materials, precursors thereof as well as the preparation and uses thereof.

First claim

1 - 20 . (canceled)

21 . An optical device comprising an optical polymer;
wherein:
the device is a Bragg grating, a phase mask, a waveguide grating router, a polymer interconnect, an echelle grating, a directional coupler, or a MachZehnder interferometer;
the optical polymer is prepared from a polymer precursor;
the polymer precursor is prepared by polymerizing a plurality of monomers of formula:
A-L-B

A comprises a vinylic group;
L is a functional linker;
B is a protecting group capable of being cleaved upon application of an external stimulus selected from the group consisting of application of an acid, a photoacid generator, heat, light irradiation, or a combination thereof;
the polymer precursor is deprotected to remove the protecting group, thereby resulting in an irreversible change in refractive index, A, and producing the optical polymer;
Δ n is greater than about 0.01.

22 . The optical device of claim 21 , wherein the polymer precursor is applied to a substrate using spin-coating.

23 . The optical device of claim 21 , wherein the polymer precursor is applied to a substrate and a photolithographic technique is used to produce a patterned optical device.

24 . The optical polymer of claim 21 , wherein A is a divinylic, multivinylic, or polyunsaturated group.

25 . The optical polymer of claim 21 , wherein A is a styrenic, acrylate, methacrylate, acrylamide, methacrylamide, or divinylbenzene.

26 . The optical polymer of claim 21 , wherein A is a vinylic group, and B is a tertbutyloxycarbonyl (BOC) or nitrobenzyl ether.

27 . The optical polymer of claim 21 , wherein L is a sulfide moiety, a selenium (Se) moiety, a tin (Sn) moiety, a titanium (Ti) moiety, a tellurium (Te) moiety, an aromatic moiety, a heteroaromatic-moiety, an aliphatic moiety, or an unsaturated moiety.

28 . The optical polymer of claim 21 , wherein:
A is a styrenic, an acrylate, a methacrylate, an acrylamide, a methacrylamide, or a divinylbenzene; and L, is a sulfide moiety, a selenium (Se) moiety, a tin (Sn) moiety, a titanium (Ti) moiety, a tellurium (Te) moiety, an aromatic moiety, a heteroaromatic moiety, an aliphatic moiety, or an unsaturated moiety

29 . The optical polymer of claim 21 , wherein a refractive index of the optical polymer is at least 0.01 greater than a refractive index of the polymer precursor.

30 . The optical polymer of claim 21 , wherein the monomer has the following structure:
