A wide-tuning-range optical delay line is demonstrated in high (2%) index contrast waveguides. This device integrates 4-stage ring resonator all-pass filters (APFs) with cascaded fixed spiral-type delay waveguides; each fixed delay path varies in length by a factor of 2 from the previous stage. A 2/spl times/2 switch separates each fixed delay and the tunable parts of the delay line. The APFs allo...Show More
Reset-free integrated polarization controller using phase shifters
C.K. Madsen;P. Oswald;M. Cappuzzo;E. Chen;L. Gomez;A. Griffin;A. Kasper;E. Laskowski;L. Stulz;A. Wong-Foy
An endless, reset-free polarization controller implemented with planar lightwave circuits using phase shifters for tuning is proposed and demonstrated. By avoiding the need for tunable polarization mode converters, simple fabrication processes and a large range of material systems can be used, since neither the electrooptic effect nor a rotatable birefringence axis are necessary for device operati...Show More
Planar lightwave circuit based reconfigurable optical add-drop multiplexer architectures and reusable subsystem module
M.P. Earnshaw;M. Cappuzzo;E. Chen;L. Gomez;A. Griffin;E. Laskowski;A. Wong-Foy;J. Soole
We describe a wide range of reconfigurable optical add-drop multiplexer architecture designs that may be implemented in standard silica-on-silicon planar lightwave circuits. This proven, reliable technology offers high performance and cost-effective solutions for reducing complex service provisioning in reconfigurable optical networks. Recent advances enable very flexible wavelength routing device...Show More

Wavelength add-drop node using silica waveguide integration
C.R. Doerr;L.W. Stulz;D.S. Levy;R. Pafchek;M. Cappuzzo;L. Gomez;A. Wong-Foy;E. Chen;E. Laskowski;G. Bogert;G. Richards
We integrated a wavelength-selective cross-connect, de-interleaver, interleaver, power combiner, and variable attenuators on one silica waveguide chip and a band demultiplexer, band multiplexer, and optical monitor on another. These two chips are used to create an eight-channel add-drop node that is expandable up to 80 channels with minimal traffic interruption by adding more of these chips.Show More
Potentially inexpensive 10-Gb/s tunable dispersion compensator with low polarization sensitivity
C.R. Doerr;M. Cappuzzo;A. Wong-Foy;L. Gomez;E. Laskowski;E. Chen
We previously reported a simple 10-Gb/s Mach-Zehnder-interferometer-type tunable dispersion compensator that requires only one control voltage. However, we used an expensive polarization-diversity scheme to achieve polarization independence. Here, we take advantage of the device symmetry and use a single half-wave plate to achieve low polarization sensitivity, saving significant cost and size. We ...Show More
Versatile integrated PMD emulation and compensation elements
C.K. Madsen;M. Cappuzzo;E.J. Laskowski;E. Chen;L. Gomez;A. Griffin;A. Wong-Foy;S. Chandrasekhar;L. Stulz;L. Buhl
Highly versatile building blocks for polarization-mode dispersion (PMD) emulation and compensation are demonstrated using tunable all-pass filters fabricated in 4%-index-contrast planar waveguides. While the all-pass filters can approximate any phase response, the complexity in setting the individual filter parameters is minimized by restricting the all-pass filter responses to realize a range of ...Show More
A hybrid MEMS-waveguide wavelength selective cross connect
D.T. Fuchs;C.R. Doerr;V.A. Aksyuk;M.E. Simon;L.W. Stulz;S. Chandrasekhar;L.L. Buhl;M. Cappuzzo;L. Gomez;A. Wong-Foy;E. Laskowski;E. Chen;R. Pafchek
A 16-channel 100-GHz-spacing wavelength selective cross connect is demonstrated using a combination of planar waveguides and MEMS piston-mirrors. Interswitch crosstalk is eliminated and switching speed is an order of magnitude faster than typical thermooptic switches. The power consumption is smaller than one microwatt per switch. An extinction ratio of 20 dB and an insertion loss of 10.6 dB are d...Show More
8 x 8 optical switch matrix using generalized Mach-Zehnder interferometers
M.P. Earnshaw;J.B.D. Soole;M. Cappuzzo;L. Gomez;E. Laskowski;A. Paunescu
We report an 8/spl times/8 strictly nonblocking optical cross connect (OXC) using multimode imaging (MMI)-based generalized Mach-Zehnder (MZ) interferometers realized in the silica-on-silicon planar waveguide system. Employing a router-selector architecture, this MMI-MZ OXC design results in a significantly smaller device than conventional directional-coupler based implementations. An average inse...Show More
Eight-wavelength add-drop filter with true reconfigurability
C.R. Doerr;L.W. Stulz;D.S. Levy;L. Gomez;M. Cappuzzo;J. Bailey;R. Long;A. Wong-Foy;E. Laskowski;E. Chen;S. Patel;T. Murphy
The authors demonstrate an integrated add-drop filter with true reconfigurability. It can drop any combination of eight wavelengths to any of eight drop ports, with less than 7 dB loss. Its features are suitable for mass production: use of standard silica waveguide technology, double-rejection switching and filtering for all paths, compactness, and power-efficient thermooptic switching.Show More

We have demonstrated an all-optical broadcast experiment in which a 10 Gbit/s RZ data signal is simultaneously converted into up to 8 different wavelengths. A single SOA with delay interferometer was used. Bit error rate measurements showed a power penalty of less than 1.5 dB for configurations with up to 8 wavelengths.Show More

P. Bernasconi;L. Stulz;J. Bailey;M. Cappuzzo;E. Chen;L. Gomez;E. Laskowski;R. Long;A. Wong-Foy
The limitations imposed by the frequency standards on the performance of N/spl times/N arrayed waveguide gratings (AWGs) are reviewed for different device layouts. An improved design that allows for an enhanced frequency accuracy of the transmission response of the device is presented and experimentally verified. The maximum deviation from the frequency standards is reduced by almost a factor of t...Show More
2 x 2 wavelength- selective cross connect capable of switching 128 channels in sets of eight
C.R. Doerr;L.W. Stulz;M. Cappuzzo;L. Gomez;A. Paunsecu;E. Laskowski;S. Chandrasekhar;L. Buhl
We present an efficient 2 /spl times/ 2 wavelength-selective cross connect that is serviceable without interrupting traffic. It can handle over a hundred channels in a compact fashion by operating on them in sets. The 50-GHz-spaced passbands are flat-topped with no gaps between them, and so it has high cascadability and can exhibit variable-bandwidth switching. It also can multicast. Index Terms-C...Show More
