SAN JOSE, Calif., Feb. 26 /PRNewswire/ -- SDL Inc.(NASDAQ:SDLI), a market
leader in high power semiconductor lasers, announced the first high
reliability multimode pump laser module for double-clad fiber amplifiers and
lasers at the Optical Fiber Communication Conference in San Jose, California.
This module is a key component in the exciting new market for high power
telecommunications laser systems based on double-clad rare earth doped fibers.
These new fiber amplifiers and lasers feature a single mode fiber core which
is pumped through a high numerical aperture cladding layer. This allows the
high powers generated with multimode semiconductor lasers to be efficiently
converted to single-mode 1550 nm power for use in communication systems. High
power fiber amplifiers and lasers are an enabling technology for multi-channel
Dense Wavelength Division Multiplexed (DWDM) systems, remote pumping of
undersea networks and optical satellite communications. SDL has been the
world leader in high power semiconductor pump lasers for over ten years and is
one of the leading manufacturers of 980 nm single mode pump lasers for erbium
doped fiber amplifiers (EDFAs).
The SDLO-4000 module delivers over 800 mW from a 100 mmm fiber at 0.22 NA.
The 14-pin butterfly package features an integral cooler which keeps the
semiconductor laser at 25 degrees C under case temperature conditions ranging
from -20 degrees C to 65 degrees C, preserving the reliability of the device.
According to Greg Dougherty, Vice President, Communications and Materials
Processing Components Group, "The experience that SDL has gained in
manufacturing 980 nm pump lasers for the EDFA market has enabled us to offer a
high reliability pump product for the emerging market that includes double
clad fiber amplifiers and lasers for telecommunications applications. Several
key manufacturing processes are shared in the two products." In order to
qualify the 100 mmm broad area semiconductor laser, extensive high temperature
accelerated multicell lifetesting was performed based on methodologies
developed for 980 nm single mode lasers. The module has been tested for
ruggedness and reliability according to strict Bellcore guidelines.
SDL designs, manufactures and markets semiconductor optoelectronic
integrated circuits, semiconductor lasers, fiber optic related products and
optoelectronic based systems. The Company's products are used in a diversity
of markets such as telecommunications, satellite communications, printing,
medical, data storage, consumer electronics, sensor, defense, materials
processing and instrument markets. |
