1. An optical multiplexer/demultiplexer, comprising:

  • a first optical waveguide operable to receive a first optical signal;

    a second optical waveguide; and

    an optical coupler operable to couple the first optical signal from the first optical waveguide to the second optical waveguide, the optical coupler comprising;

    an optical switching wedge;

    a coupling waveguide adapted to transmit light from the optical switching wedge to the second optical waveguide; and

    a piezoelectric actuator operable to move the optical switching wedge between a first position, in which the optical switching wedge is optically coupled to the first optical waveguide, and a second position, in which the optical switching wedge is optically uncoupled from the first optical waveguide.
