Description

The

10

Gbits/s

dual-drive

modulator

is

designed

for

long-wavelength,

single-mode

external

amplitude

modulation

applications

.

It

uses

an

integrated

Mach-Zehnder

configuration

to

convert

single polarization

CW

light

from

a

semiconductor

(DFB)

laser

into

a

time-varying

optical

output

signal

.

Agere

.

also

offers

a 10

mW

CW

laser

with

polarization-maintaining

fiber

(D2525)

to

use

as a

source

for

the

modulator

.

The

patented

dual-drive

configuration

and

Ti-diffusion

process

is

a

standard

feature

on

this

modulator

.

With

this

design

advantage,

balanced

drive voltage

produces

zero-chirp

modulation

operation

.

The

package

is

hermetic

to

protect

the

LiNb03

die

from

the

environment

.

Novel

processing techniques

now

make

it

possible

to

achieve

20-year

operation

with

little

drift

in

the

dc-bias

point

.

Other

standard

features

include

PANDA-type

polarization-maintaining

fiber

(PMF)

as

the

optical

input

fiber

and

standard

single-mode

for

the

output

fiber

.

The

device

has

an

FC-type connector

on

the

input

and

an

LC

type

con-

nector

on

the output

.
