Hybrid Integration Offers Benefits of Low Cost and Small Size
WaveSplitter Technologies, Inc. and Gemfire Corporation
In today's environment, carrier spending is very conservative. System
vendors must squeeze cost from their product, while still differentiating
their system from competitors. Optical components based on hybrid
integration, the chip-to-chip integration of hybrid technologies,
are a way to meet this challenge.

Hybrid integration optimizes
PLC module design
Dr. Jerry Bautista, Dr. Kevin Sullivan, Dr. Bob Shine, and Bo Rotoloni
Integration of multiple devices is currently the most effective means
of controlling costs and delivering functionality. Hybrid integration
optimizes performance and overall yield of components based on planar
lightwave circuits (PLCs).

Integrated interleaver technology enables
high performance in DWDM systems
Joseph Chon, Andrew Zeng, Phil Peters, Benjamin Jian, Ariel Luo, and
Kevin Sullivan
A 160-channel DWDM system integrating a 1x4 25-GHz nonlinear Fourier
Filter Flat-top (F3T) interleaver with four 1x40 100-GHz AWGs was
investigated for 10 Gb/S PRBS laser-detuning transmission experiments
and OC-192 network applications. Telcordia 1221 testing results conclude
the F3T interleaver is qualified for central office (CO) operation.
12.5 GHz F3T interleavers capable of Mux/DeMux >320 channels were
also demonstrated in this work.

Raman components gain some new requirements
Dr. Jerry Bautista and Dr. Bob Shine
Despite using components similar to those used in EDFAs, Raman amplifiers
increase the power-handling requirement of passive devices along with
creating other demands.

PLC platform addresses emerging component requirements
Dr. Jerry Bautista, Dr. Kevin Sullivan and Dr. Bob Shine
WDM has enabled capacity on fiber-based networks to increase dramatically.
Initial WDM systems deployed in 1996 used four wavelength channels
spaced 400 GHz apart; systems deployed today offer 160 channels spaced
50 GHz apart.

Interleavers make high-channel-count systems economical
Dr. Jerry Bautista and Dr. Bob Shine
As most people reading Lightwave already know, the Internet has created
an explosion in the amount of information transmitted over telecommunications
networks. According to the research firm RHK Inc. (San Francisco),
roughly 1 million terabits/month are currently transmitted over tecommunication
networks, with a forecasted growth to >15 million terabits/month
in 2003.

Multiplexers bring DWDM to metro/access markets
Dr. Jerry Bautista
The need for increased bandwidth has driven system providers to offer
ever-increasing channel counts at narrower channel spacings. Long-haul
systems continue to be deployed with at least 16 channels and often
with the capability of 40 or more channels. |

Low-Loss Flat-Top 50-GHz DWDM and Add/Drop Modules
Using All-Fiber Fourier Filters
Chi-hung Huang, Yuan Li, Jin Chen, Erkin Sidick, Joseph Chon, Dr.
Kevin Sullivan, and Dr. Jerry Bautista
While DWDM is being widely deployed in the modern optical telecommunications
systems, increasing the channel counts is a major continuing effort
to increase an even larger traffic bandwidth. While extending the
communication window to the S and L bands is an option, the most common
approach is to decrease the wavelength spacing between channels.

Dr. Jerry Bautista
An alternative approach of making all fiber-based optical add and
drop modulator is developed. This approach utilizes a high spatial
resolution retro-reflectometric technology and the well-established
optical fiber fusion splicing process to combine a pair of matched
fiber Bragg gratings which are readily available with two fiber-fused
3dB couplers into a balanced Mach-Zehnder interferometer.
