Abstract:
1. An electro-optic semiconductor device comprising: a beam propagation structure having an input optical face and an output optical face distinct from the input optical face; an active region disposed in the beam propagation structure and having an optical response, wherein the optical response can be altered by varying an electric field in the active region; wherein the active region is disposed substantially parallel to an internally reflective face of the beam propagation structure; wherein the beam propagation structure defines an internal optical beam path of an optical beam propagating within the device from the input face to the output face; wherein the beam propagation structure defines an external optical beam path for light incident on the input optical face and for light emitted from the output optical face; wherein the internal optical beam path includes a reflection from the internally reflective face of the beam propagation structure at an oblique angle of incidence; wherein at least one of the input and output optical faces is not parallel to the internally reflective face; wherein the optical beam path makes an oblique angle with respect to at least one of the input and output optical faces.
