40 Gbits/s Lithium Niobate Electro-Optic Modulator
Applications
s Digital high-speed telecommunications:
— SONET OC-768
— Undersea communications
s Internet data communications
s SONET test equipment
The Lithium Niobate 40 Gbits/s Modulator (2625C) is a higher-
speed addition to the Agere Systems’ family of modulators
that also includes 10 Gbits/s and 20 Gbits/s versions.
Features
s Ti-diffusion process
s Dual-drive technology
s Thin-film, 50 termination in package for minimal
reflections
s Low modulation voltages
s Tested to Telcordia Technologies * 468
s Angled interfaces for minimal optical reflections
s Hermetic package
s Separate dc bias electrode
Description
Representing the latest advancements in high-speed
lithium niobate technology, the 40 Gbits/s electro-
optic modulator is designed for long-wavelength,
single-mode, external amplitude modulation applica-
tions. It uses an integrated Mach-Zehnder configura-
tion to convert single polarization CW light from a
semiconductor (DFB) laser into a time-varying optical
output signal. Using the source in the CW mode elim-
inates the need for demanding, high-speed perfor-
mance from the laser and reduces its cost.
The dual-drive design inherently offers the capability
to adjust the phase of the voltages on the electrodes,
which produces zero-chirp modulation operation.
The modulator is tested to, and meets the intent of,
TR-NWT-00468.
Benefits
s Excellent long-term bias stability over a full opera-
tional temperature range of 0 °C to 70 °C
s Adjustable chirp for long distances at high bit rates
s Internal polarizer
