Abstract (en)
[origin: EP2006951A1] A compensated waveguide device comprises waveguide having first coefficient of thermal expansion (CTE) comprising long sides (6, 7), short sides (4, 5) having median axis and longitudinal ribs (2, 3) having surface common with over 1/2 width of short side and being off-axis relative to median axis to cut in body of waveguide, and rotation unit in contact with longitudinal rib to deform short side. The rotation unit comprises prongs (8, 9, 10, 11) of low thermal deformability having second CTE smaller than first CTE by a factor >= 5 and a brace and frame (12) having CTE larger than second CTE.
