Through the efforts of many research groups and consortia over the last several years, the acousto-optic tunable filter has evolved into a device capable of high-performance wavelength-selective optical switching and wavelength routing in dense WDM s

Silver lithium ion exchange has been found to produce optical waveguides in x-cut LiTaO(3)at temperatures well below the Curie temperature, producing waveguides that require no repoling. This process is attractive for integrated optics because LiTaO(

Large-scale WDM systems contain wavelength-selective filters, switches and multiplexers which must be tolerant of moderate wavelength channel misalignment and can be cascaded without severe accumulated shrinkage of the effective passband width. These

Wavelength-division multiplexing (WDM) can greatly increase the connectivity of a fiber-optic network because information can be aggregated and routed on a wavelength-by-wavelength basis, by using wavelength-selective passive or active switches. In p

The optical packaging of receiver arrays presents two difficult problems, one common to other arrays, and one peculiar to those involving detectors. Coupling light between arrays is typically more challenging than coupling to individual components, b

We have used an asymmetric x-junction (ASX) as a polarization-independent sum and difference beam combiner. This component is integrable with adiabatic polarization splitters to build a fully passive integrated front end for a polarization-diversity

We report the observation of upconversion fluorescence in an erbium/ytterbium-doped silicate glass. Although upconversion fluorescence has previously been observed in rare-earth doped fluoride glasses,1,2 and recently in gallate and tellurite glasses

For the first time, to our knowledge, orthogonal proton-exchange polarizers have been fabricated on a single LiNbO3 substrate, allowing for the total integration of two acoustically tunable optical filters (ATOFs). This is a major step toward the dev

The use of epitaxial lift-off1 to incorporate active optoelectronic components on low loss and inexpensive nonsemiconductor optical waveguides offers an attractive technology for high-performance integrated optics. Using this technique, we have previ
