1. A device comprising:
a phononic crystal, the phononic crystal including:
a phononic beam splitter, the phononic beam splitter adapted to receive first and second phononic input signals, to couple approximately 50% of the first phononic signal to each of first and second phononic beam splitter outputs, and to couple approximately 50% of the second phononic signal to each of first and second phononic beam splitter outputs;
a first phononic phase shifter, the first phononic phase shifter coupled to the first phononic beam splitter output and adapted to receive a first phononic beam splitter output signal therefrom, the first phononic phase shifter adapted to induce a first phase shift in the first phononic beam splitter output signal, and to couple the phase shifted first phononic beam splitter output signal to a first phononic phase shifter output;
a second phononic phase shifter, the second phononic phase shifter coupled to the second phononic beam splitter output and adapted to receive a second phononic beam splitter output signal therefrom, the second phononic phase shifter adapted to induce a second phase shift in the second phononic beam splitter output signal, and to couple the phase shifted second phononic beam splitter output signal to a second phononic phase shifter output; and
a phononic beam combiner, a first input to the phononic beam combiner coupled to the first phononic phase shifter output and adapted to receive the first phase shifted first phononic beam splitter output signal therefrom, a second input to the phononic beam combiner coupled to the second phononic phase shifter output and adapted to receive the second phase shifted second phononic beam splitter output signal therefrom, the phononic beam combiner adapted to couple a first portion of the first phase shifted first phononic beam splitter output signal to a first phononic beam combiner output and a remainder of the first phase shifted first phononic beam splitter output signal to a second phononic beam combiner output, and to couple a first portion of the second phase shifted second phononic beam splitter output signal to the first phononic beam combiner output and a remainder of the second phase shifted second phononic beam splitter output signal to the second phononic beam combiner output.
