Abstract:
A waveguide device comprising:(i) at least one pair of optical fiber waveguides located such that (a) light radiation propagating through one of said waveguides will be at least partially coupled to a corresponding waveguide and, (b) said optical fiber waveguides are separated by a gap of about 2 &mgr;m to about 500 &mgr;m, said optical fiber waveguides having dn/dT that is larger than 0.0/C.Â°; (ii) at least one, another non-planar waveguide connecting said at least one pair of optical fiber waveguides, said another non-planar waveguide having dn/dT of âˆ’2Ã—10âˆ’4/C.Â° to âˆ’4Ã—10âˆ’4/C.Â°.
