Santur Introduces Full Band Tunable Lasers with Integrated Modulator
Santur Corporation announced that they have introduced Integrated Tunable Transmitter Assemblies (ITTA) which uses Santur’s Tunable Laser Mach-Zehnder Modulator (TLMZ) as the key component.
The ITTA and TLMZ are a new generation of compact C and L band widely tunable 10 Gb/s modulated transmitters. The TLMZ integrates Santur’s widely tunable DFB array technology with a semiconductor Mach-Zehnder modulator. There are two types of modulators, one is chirped for applications requiring dispersion tolerance up to 1600 ps/nm and a zero chirp version for applications where the dispersion tolerance is 1200 ps/nm.
Integration of the tunable laser with an InP Mach-Zehnder modulator provides for a highly efficient, small form factor component that can replace CW lasers and LiNbO3 modulators. The small size of the TLMZ butterfly can also be used to replace Externally Modulated Lasers (EMLs) in small form factor transponders, thus enabling smaller, full band tunable transponders than are currently available.
Ideally suited for use in a wide variety of DWDM systems, the Santur ITTA or TLMZ provides the best combination of performance features available. They offer a unique combination of modulated optical power, wide tunability, and excellent modulation characteristics. Excellent performance characteristics, reliability, ease of manufacture, and economies of scale derived from Santur’s exclusive, proven design, differentiate this product from others in the industry.
For users interested in module level products, the ITTA, which includes the control electronics is available. For users that are interested in more compact designs, the TLMZ at the butterfly level is the best choice.
