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.
Bookham has taken the unique step of mounting specially designed optical thin film filters required for multiplexing into a package that is more compact and optically efficient than traditional solutions.
ZoroLight multiplexes red, blue and green LED signals to enable DLP (digital light processor) projection devices and requires minimum alignment during light engine assembly by customers.
"LED-based projection systems are a growth market and one that Bookham is well positioned to support", explained Bruce Kuhlmann, Director of Global Sales - Thin Films, Bookham.

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.
"As the number one supplier of thin film filters to the telecom industry, we have built up extensive experience in combining multiple wavelengths of light efficiently".
"By using telecom thin film filter technology, and the unique production processes we have developed, we are able to bring theatre quality, high performance optics to the projection display market and package them in such a way that OEMs can use them seamlessly within their own offering".
Bookham has developed fully automated thin film and assembly processes, which create higher quality optics than competitive systems.
The Bookham patented AED (advanced energetic deposition) automated thin film optical coating technology produces precision optical filters with ultralow defect levels and higher light throughput, tighter wavelength control, high volume and low cost.
"We believe that our production processes are unique within the display industry", said Kuhlmann.
"They enable greater consistency and reliability of supply - factors that have contributed to our leading position as a supplier to the telecom sector and growth in the display sector".
Bookham will be showing ZoroLight and its full line of ColorLoc thin film components for display optics, at Infocomm and SID this week.
The portfolio includes colour filter wheels, which offer optimised colour management and enhanced brightness in high performance DLP imaging applications; all dielectric light pipes for low loss light homogenisation; UV/IR blockers, which prevent harmful ultraviolet and infrared radiation from degrading a projection system's performance; anti-reflection coatings (ARs); front surface mirrors (FSMs) for microdisplay engine beam-folding; dichroics for colour separation and combining; and custom filters and assemblies for LED illumination.
