Abstract
We present the realization and characterization of a distributed feedback (DFB) laser matrix realized on an Er/Yb codoped glass substrate. Output power characteristics such as power efficiency and relative intensity noise (RIN) 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 is achieved and a RIN falling below –150 dB/Hz after 4 MHz is 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, a 1.3-GHz/°C temperature dependency of the comb of wavelength is determined.
