Abstract

The design features and advantages of a discrete wavelength tunable laser, demonstrated by microelectromechanical systems (MEMS) technology, were analyzed. A semiconductor laser, a single-mode optical fiber and a MEMS mirror were integrated onto a single chip to obtain the laser system. A single longitudinal mode was maintained while tuning the wavelength of a monolithic MEMS tunable laser by discrete steps to discrete values. The wide tuning range, fast tuning speed, high wavelength and easy monolithic integration were presented as the benefits from DWT lasers. It was found that the laser was tuned at a tuning range of 13.5 nm and a sweeping speed of about 1 ms.
