Abstract: A waveguide structure for use with a pump laser is disclosed that is designed to counteract the decrease in pump power density. The waveguide structure may comprise an erbium-doped waveguide amplifier, a nonlinear waveguide wavelength converter device, or an optical fiber. The waveguide structure has a waveguide region that is tapered over a pump propagation distance, said distance being defined as a predetermined distance between a first pump site and a second pump site over which the pump light is propagated for signal amplification or conversion. The taper reduces the depletion in pump power as compared with prior art systems and may be kept substantially constant over the pump propagation length, thereby counteracting pump depletion.

Abstract: An optical switching device comprises: a light guide including a total reflection plane capable of totally reflecting light thereby transmitting the light; a switching part capable of, at a position where its extraction plane is in close contact with the total reflection plane, capturing evanescent light and reflecting the captured light thereby outputting it; and a driving part for driving the optical switching part. The light guide, the switching part, and the driving part are laminated in this order into a multilayer structure. The employment of the multilayer structure makes it possible to optimize the respective layers independently of one another. The extracted light does not pass through the driving part. This allows the driving part to be optimized so as to achieve an optical switching device capable of operating at a high speed with low power consumption. Thus, it is possible to provide a low-loss and high-contrast optical switching device using an evanescent wave, which can respond at a high speed.

Abstract: Tunable add-drop and cross connect devices include materials with negative dependence of refractive index on temperature and temperature independent coincidence between resonator modes and a set of specified frequencies, e.g. for DWDM telecommunications channels. The free spectral range may be adjusted to equal a rational fraction of the specified frequency interval. The operating frequency may be selected without substantially tuning the cavity modes by a thermo-optically tuned feedback element. This can be accomplished by means of a waveguide pair with differential thermal response. Tuning may also be accomplished by applying an electric field across an electro-optic liquid crystal portion of a waveguide pair. The resonator and coupled waveguide pair arrangement may be used as a communications signal receiver where the coupling strength is optical frequency tuned by the applied thermal or electrical field.
