Abstract
Abstract Disclosed is the use of a polymer material in an optical waveguide structure. The polymer material may be used in either the cladding (120) or the core material (105) of an optical waveguide. The use of polymer material as such is advantageous in that the index of refraction of polymer material varies significantly with changing temperature. The polymer material is subjected to a heating mechanism (205) and/or a cooling mechanism (210) to manipulate the index of refraction as desired.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
60 words
A waveguide, comprising: a core having a first index of refraction, said first
index of refraction varying upon the application of heat according to
a first thermal coefficient; and a polymer cladding material in contact with the core, said
cladding material having a second index of refraction which varies
upon the application of heat according to a second thermal
coefficient.
Claim 2
Dependent Claim
24 words
The waveguide of claim 1, wherein said second thermal
coefficient is greater than said first thermal coefficient
by a factor of at least 5.
Claim 3
Dependent Claim
38 words
The waveguide of claim □, wherein said second index of
refraction varies between a first value that is greater than the first
index of refraction and a second value that is less than the first
index of refraction.
Claim 4
Dependent Claim
17 words
The waveguide of claim 1, further comprising an electrical
heating element coupled to the polymer cladding material.
Claim 5
Dependent Claim
22 words
The waveguide of claim 1, further comprising a source of
laser radiation positioned to direct laser radiation at the polymer
cladding material.
Claim 6
Dependent Claim
16 words
The waveguide of claim 1, further comprising a thermo-electric
cooler coupled to the polymer cladding material.
Claim 7
Dependent Claim
17 words
The waveguide of claim 2, further comprising an electrical
heating element coupled to the polymer cladding material.
Claim 8
Dependent Claim
22 words
The waveguide of claim 2, further comprising a source of
laser radiation positioned to direct laser radiation at the polymer
cladding material.
Claim 9
Dependent Claim
59 words
A waveguide, comprising: a polymer core having a first index of refraction, said
first index of refraction varying upon the application of heat
according to a first thermal coefficient; and a cladding material in contact with the core, said
cladding material having a second index of refraction which varies
upon the application of heat according to second thermal coefficient.
