Abstract: A substantially planar waveguide for dynamically controlling the out-of-plane angle at which a light beam exits the waveguide. Generally, liquid crystal materials may be disposed within a waveguide in a cladding proximate or adjacent to a core layer of the waveguide. In one example, the waveguide may contain one or more taper regions such that the light beam exits the waveguide and propagates out-of-the-plane of the waveguide into an out-coupling medium at a propagation angle. In one example, the waveguide may contain one or more electrodes onto which one or more voltages may be applied. The magnitude of the propagation angle may be electronically controlled by stored by controlling or altering the magnitude of the one or more applied voltages.

Abstract: Disclosed herein is a tunable wavelength optical transmission module, the wavelength of which can be tuned over the wide wavelength region of a C band and which can be implemented at a low price and, thus, can be applied to an optical network terminal. Bragg gratings having different grating periods are arranged in parallel or series and the temperatures of Bragg grating regions are then controlled, so that the wavelength of an optical signal can be tuned over a wide wavelength range through the small variation in temperature.

Abstract: Methods of attenuating, delaying the phase, and otherwise controlling an optical signal propagating along a waveguide are provided. According to one method, a variable optical attenuator structure is provided comprising a waveguide core, a cladding, an electrooptic polymer, and a set of control electrodes. The core, the cladding, and the electrooptic polymer are configured such that an increase in the index of refraction of the polymer causes a substantial portion of an optical signal propagating along the waveguide core to couple into a relatively high index region of the electrooptic polymer above the waveguide core, so as to inhibit return of the coupled signal to the waveguide core. Another embodiment of the present invention introduces a phase delay in the coupled optical signal and permits return of the coupled signal to the waveguide core. An additional embodiment contemplates the use of a ridge waveguide structure to enable control of the optical signal. Additional embodiments are disclosed and claimed.
