Abstract

The fabrication of a device which operates beyond the cutoff of the antisymmetric supermode of a coupler is described. The result is a coupler, henceforth referred to as a Superflat™, which holds its coupling ratio to +/- 1% over the wavelength range of 1200 nm to 1600 nm, and yet exhibits losses as low as 0.3 dB. Applications in test and measurement, CATV, and as an all-fiber, fixed attenuator are discussed.
