Abstract
An emitting device is intended for delivering photons with a chosen wavelength. This emitting device includes an InP substrate with a directly modulated laser arranged for generating photons modulated by a non-return-to-zero modulation to produce data to be transmitted, a passive ring resonator monolithically integrated with the directly modulated laser and having a resonance amongst several ones that is used for filtering a zero level induced by the data modulation, and a tuning means arranged along the directly modulated laser and/or around the ring resonator to tune the photon wavelength and/or the ring resonator resonance used for filtering.
