Abstract
Wavelength conversion devices will play an important role in future optical transmission or optical signal processing systems. Wavelength conversion in the 1.55-µm range has been achieved using single-mode semiconductor lasers [1]-[6] or semiconductor laser amplifiers. [7]-[9] From a systems point of view, it is preferable to have a converted signal wavelength that is arbitrarily selectable. Wavelength conversion using semiconductor laser amplifiers alone cannot change the converted signal wavelength. [7]-[9] On the other hand, tunable wavelength conversion using single-mode lasers can easily be performed and was achieved by using a multielectrode distributed feedback (DFB) laser [1] and by using a distributed Bragg reflector (DBR) laser.
