摘要
An emitting device (1) is intended for delivering photons with a chosen wavelength. This emitting device (1) comprises an InP substrate (2) with a directly modulated laser (3) arranged for generating photons modulated by a non-return-to-zero modulation to produce data to be transmitted, a passive ring resonator (4) monolithically integrated with the directly modulated laser (3) and having a resonance amongst several ones that is used for filtering a zero level induced by the data modulation, and a tuning means (5) arranged along the directly modulated laser (3) and/or around the ring resonator (4) to tune the photon wavelength and/or the ring resonator resonance used for filtering.
