The multimode laser diode allows service providers to extend triple-play service delivery to fibre customers located further away from the central office or the cable head-end.
Modulator tunes lasers up to 40Gbit/s
Reduced size InP MZ platform will allow Bookham to offer 40Gbit/s products in smaller footprints compared with existing 40Gbit/s offerings employing larger optics.
The new multimode pump laser module allows a significant step forward in the design of current and next generation fibre laser systems by providing increased brightness at lower cost and with high reliability.
The uncooled module, incorporating the latest generation of multimode pump laser chips from the Bookham Zurich facility, delivers above 7W light output power from a multimode fibre with 105um core diameter and 0.15 or 0.22 numerical aperture.
Powers of more than 10W out of fibre have been successfully achieved, demonstrating the capability of the design.
The hermetic module with floating anode/cathode is available in various packaging form factors.
"This is a significant advance in high power uncooled multimode pump performance", said Steve Turley, Chief Commercial Officer.
"It is another example of Bookham leadership delivering exceptional value to a broad range of industrial laser markets".
One of the core technologies driving advances in power and reliability is the Bookham proprietary E2 process, which passivates the laser's front mirror.
The aim of this passivation is to prevent catastrophic optical mirror damage (COMD), which is otherwise a common problem in the development of high brightness GaAs laser diodes.
The new pump module will be displayed at the Bookham stand (B1.509) at Laser 2005 in Munich.
Bookham will also present an invited technical paper at the exhibition on the latest results of the next generation chip development: 20W from a 90um aperture laser diode.
