Abstract
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° to 92° relative to the device and that is toward a location above or below the device.
