Nortel (Ottawa, ON, Canada) has announced the development of a wavelength-locked, high-power tunable laser for DWDM applications. The prototype can be tuned over the 1530- to 1560-nm range, as well as to bandwidths as high as 1600 nm. Nortel sources would not speculate when the technology would be available as a commercial product. But the company is discussing the technology with prospective customers concerning potential tradeoffs in tuning range, control, price, and other factors. The ability to retune the laser in the field, possibly remotely, is also a potential feature.
