A discrete wavelength tunable laser has been demonstrated using microelectromechanical systems (MEMS) technology. The laser system is formed by integrating a semiconductor laser, a single-mode optical fiber, and a MEMS mirror onto a single chip. It has overall dimensions of 1.5 mmx1 mmx0.6 mm (not including the optical fiber), and can be tuned to sweep a wavelength range of 13.5 nm within 1 ms. Unlike the conventional continuously tunable lasers, the laser system enables discrete wavelength tuning by making use of a short external cavity and weak feedback.
