Polarization independent acousto-optic tunable filters (PIAOTF's) can operate as transparent wavelength-selective crossconnects to route signals in wavelength division multiplexed optical networks. In this paper, a new low power PIAOTF is characteriz

The first system demonstration of a polarization-independent acoustooptic filter centered at 1500 nm with a narrow bandpass (1.3 nm) and broad continuous tuning range (145 nm) is reported. It is shown that filtered transmission of 990-Mb/s pseudorand

Crosstalk in acousto-optic switches is modulated at frequencies related to that of the acoustic waves driving the device. We present measurements of the modulation, a brief discussion of its causes and examples of its effect on system performance.

Because they are capable of switching several wavelengths simultaneously,1 acousto-optic tunable filters (AOTF) are under consideration as wavelength-routing switches in WDM networks. However, our recent measurements (Fig. 1) of the complete pass or

With its wide tunability and multiple-channel switching capability, the integrated version of acousto-optic tunable filters (AOTF’s) has shown healthy development in recent years for wavelength-division-multiplexing (WDM) optical-communication netw
Wavelength routing crossconnects are considered the core of WDM optical networks. They consist of optical switches independently rearrangeable for each wavelength channel and for any input- output configuration so that any path can be chosen almost a

The often‐observed extreme asymmetry in the sidelobe spectra of integrated acousto‐optic filters exacerbates cross talk between wavelength‐multiplexed optical channels. We explain the source of this asymmetry in terms of a systematic even‐ord

A wavelength-selective switch is a fiber interconnection machine which has the property that incoming fiber channels can be connected in completely different ways for each wavelength channel they carry. The cumbersome construction of this function re

An integrated-optic polarization splitter is a necessary component in many integrated photonic devices, particularly in those devices, such as coherent receivers and optical filters, which achieve polarization independence by employing a polarization

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
