TUNABLE EMITTING DEVICE WITH A DIRECTLY MODULATED LASER COUPLED TO A RING RESONATOR

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.

1. Emitting device for delivering photons with a chosen wavelength, said emitting device comprising:
i) 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, the active structure of the directly modulated laser being epitaxially grown on the InP substrate, ii) a passive ring resonator being defined in a passive section of the InP substrate, said passive ring resonator being monolithically integrated with said directly modulated laser by carrying out a p-doped re-growth both in the active and passive sections of the InP substrate followed by a hydrogenation of the passive section of the InP substrate for rendering the p-doping of the re-growth inactive, said passive ring resonator having a resonance amongst several ones that is used for filtering a zero level induced by said data modulation, and iii) a tuning means arranged along said directly modulated laser and/or around said ring resonator to tune the photon wavelength and/or said ring resonator resonance used for filtering.
