Paper Abstract

This paper presents the realization and characerization of a matrix of DFB lasers realized by ion-exchange on Er/Yb codoped glass substrate. Output power characteristics such as power efficiency and Relative Intensity Noise are presented, wavelength characteristics including linewidth, wavelength stability versus temperature and emission wavelength calibration are also investigated. Concerning output power, a 4.5 mW fiber coupled emission was achieved and a low RIN falling below -150bB/Hz after 4 MHz was measured. The matrix contains 15 lasers emitting at 100 or 25 GHz spaced frequencies with a very narrow linewidth measured to be 3 kHz. Finally, the temperature dependency of the comb of wavelength is measured to be 1.3 GHz/°C.
