A linearized modulator based on the Mach-Zehnder interferometer (MZI) loaded with a second-order allpass microring resonator is proposed and analyzed. The device is shown to exhibit much smaller intermodulation distortion than standard Mach-Zehnder m

An optical waveguide MEMS switch fabricated on an indium phosphide (InP) substrate for operation at 1550 nm wavelength is presented. Compared to other MEMS optical switches, which typically use relatively large mirrors or long end-coupled waveguides,

We report propagation loss measurements in single-mode GaAs-AlGaAs racetrack microresonators with bending radii from 2.7 /spl mu/m to 9.7 /spl mu/m. The experimental data were found to be in good agreement with a physical-loss model which accounts fo

Multiphoton absorption polymerization (MAP) allows for rapid prototyping of microscale optical devices. We have created high-performance, single-mode optical waveguides and have demonstrated the coupling of these structures to optical fibers for use

Microresonator filters reported so far have been all-pole-type filters. We report two experimental realizations of zero-type (notch) filters using GaAs-AlGaAs microring resonators. The first is a ring coupled to one side of a Mach-Zehnder interferome

1407_69Using a simple mean field model of the electron-electron interaction, study has been done of the effect of space charge in a planar diode. Results show, in particular, that the classical value for the limiting current in such a diode can be ex

Cyclical propagation of light in circular arrays of microring resonators is exploited to realize efficient slow-wave structures with large group-delay enhancements. Devices with maximally-flat group-delay responses are designed for applications in di

We demonstrate all-optical pump-probe switching in electrically-pumped microdisks fabricated on InGaAsP/InP using gain-saturation optical non-linearity to achieve switching at lower powers than in passive devices. A pseudo-microdisk design combines t
