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 35):
A waveguide Y-splitter comprising:\n an input port for launching an input beam of light; an input waveguide including a longitudinal axis, capable of providing adiabatic expansion of the input beam of light from the input port to an output end, which has a width that supports a fundamental mode and a second order mode; a mode-matching junction for splitting the input beam of light, and capable of propagating the fundamental mode of the incoming light to a fundamental super mode; first and second output waveguides extending from the mode matching junction on either side of the longitudinal axis, and separated by a gap, wherein each of the first and second output waveguides includes an initial section, including a width 1.3\u00d7 to 2.0\u00d7 smaller than a width of the input waveguide, whereby the initial sections and the gap are capable of supporting the super mode of the incoming beam of light, which spans the initial sections of the first and second output waveguides and the gap.
