Abstract:
A mode-matched waveguide Y-junction with balanced or unbalanced splitting comprises an input waveguide, expanding from an input end to an output end, for expanding the input beam of light along a longitudinal axis; first and second output waveguides extending from the output end of the input waveguide separated by a gap. Ideally, each of the first and second output waveguides includes an initial section capable of supporting a fundamental super mode, and having an inner wall substantially parallel to the longitudinal axis, and a mode splitting section extending from the initial section at an acute angle to the longitudinal axis.

Claim (Index 21):
A method of splitting a beam of light comprising:\n launching an input beam of light via an input port; adiabatically expanding the input beam in an input waveguide including a longitudinal axis, extending from the input port to an output end, whereby the input waveguide includes a width that supports a fundamental mode and a second order mode; propagating the fundamental mode to a mode-matching junction, and exciting a fundamental super mode in initial sections of first and second output waveguides; supporting the super mode of the input beam, while spanning the initial sections of the first and second output waveguides and a gap therebetween, the first and second output waveguides including the initial sections extending from the output end of the input waveguide separated by the gap; and splitting the input beam of light into first and second output beams between the first and second output waveguides, respectively.
