The spectral evolution and transitional behavior of the odd harmonic windows in a broadly tuned electrooptic Solc filter are described theoretically and demonstrated experimentally. We show how the fundamental and all the odd harmonic passbands split and eventually merge in pairs with nearest neighbors to become even harmonics of the fundamental λf as the principal pass wavelength λp is tuned from λp = λf to λp ≫ λf.
