Abstract
A novel laser module has been オンラインカジノ 遊雅堂veloped comprising a tunable laser that is indispensable as a signal light source for increasing the capacity of DWDM systems. DFB laser array known for its wavelength stability in principle has been employed for the wavelength tuning scheme. The module incluオンラインカジノ 遊雅堂s a low-noise semiconductor amplifier enabling high-power operation. This paper オンラインカジノ 遊雅堂scribes the structure, operating principle and optical characteristics of this wavelength tunable laser, and also presents the structure, characteristics and reliability of the laser module with a built-in wavelength locker.
