An optical device includes a waveguide immobilized on a base. The device
includes a port configured to receive light signals from the waveguide
such that the light signals travel through the port. The light signals
enter the port traveling in a first direction. The port is configured to
change the direction of the light signals from the first direction to a
second direction that is toward a location above the device or below the
device. The device also includes a wedge configured to receive the light
signals from the port such that the light signals travel through the
wedge and then exit the wedge traveling in a direction that is at an
angle in a range of 88.degree. to 92.degree. relative to the device and
that is toward a location above or below the device.
