Abstract

Configurations for a light splitting device used for light splitting over an operating bandwidth of wavelengths are disclosed. The light splitting device may include a first coupler and a second coupler, where the first coupler has a first splitting power relationship and the second coupler has a second splitting power relationship and the first and second splitting power relationships are complementary to one another over the operating bandwidth of wavelengths. The light splitting device may further include a phase delay positioned between the first and second couplers. The phase delay may result in the output light having an approximately even optical power distribution across the operating bandwidth of wavelengths. In some embodiments, the first and second couplers may be directional couplers and, in other embodiments, the first and second couplers may be tapered couplers.
