Tunable laser technology demonstrated at
ECOC
Bookham is to demonstrate the power and application of its tunable laser technology at the European Conference and Exhibition on Optical Communications (ECOC), which is being held in Glasgow, UK.
Bookham, a provider of optical components, modules and subsystems, is to demonstrate the power and application of its tunable laser technology at the European Conference and Exhibition on Optical Communications (ECOC), which is being held in Glasgow, UK Bookham will be presenting three papers at ECOC, which together illustrate how far tunable laser technology has developed and the likely extent of its future application

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.
"We are driving tunability into the mainstream volume markets through a combination of very robust chip technologies coupled with low cost, high volume manufacturing in Shenzhen", said Adam Price, Product Line Management Director of High End Optics at Bookham.
"The three papers we are presenting at ECOC demonstrate the technical excellence of the Bookham chip and module platforms and show their capability over the full spectrum of applications".
The first paper will focus on the demonstration of equivalent performance in L band lasers to that previously reported for C band lasers.

The 2.2 x 3in footprint enables network equipment manufacturers to increase port density, placing two SFF transponders on a card where only one LFF would fit.
Bar supports laser systems
The VHB bar has a power output of 80W (up to four times the brightness of a typical 10mm bar) and measures only 3.2mm in width.
A pair of laser modules is shown to give complete coverage of C and L band with power levels greater than 16.5dB (ex facet, greater than 13dBm ex module) and side mode suppression ratio (SMSR) greater than 45dB.
The second paper is a detailed analysis of the intrinsic noise associated with the DSDBR laser platform, showing that low levels of frequency modulation noise generated by the lasers, which give negligible effect on dispersion penalty even for very long haul systems using electronic dispersion mitigation.
The third paper presents design and packaging results on a compact butterfly 10Gbit/s transmitter, including the company's DSDBR laser and indium phosphide (InP) Mach-Zehnder (MZ) modulator, showing excellent power, reach and eye quality over the full C band.
"The result of our 10Gbit/s transmitter is a breakthrough performance in such a small package".
"We will be bringing this product to market early next year, and are now engaging with key customers", said Price.
"The packaging technology for this product is derived from our range of fixed wavelength InP transmitters, of which some 75,000 have already been manufactured".
"The very high performance of the new tunable component, coupled with its minimal butterfly footprint, will open the way to widespread cost-effective tunability in many metro and long-haul applications".
Bookham will be showing a range of tunable products on Stand 438 at ECOC, including its DS-DBR integrated tunable laser assembly (iTLA), wideband tunable compact Mach-Zehnder (MZ) and compact MZ.
