2 mW CW singlemode operation of a tunable 1550nm verticalcavity surface emitting laser with 50 nm tuning range

Abstract

A tunable 1550 nm vertical cavity surface emitting laser with 2 mW of tunable CW output power and a 50 nm tuning range has been demonstrated. The device is a micro-electromechanical structure where the top curved mirror is displaced by a voltage-induced electrostatic force. The cavity is designed for operation under optical pumping at 980 nm wavelength.
