| 发明名称 | Method for controlling the wavelength of a laser source | ||
| 摘要 | The present invention concerns a method for controlling the emitting wavelength of a laser source (10) for a passive optical network, the laser source (10) comprising: a first Bragg mirror (12),a second Bragg mirror (14),a cavity (16) delimited by both Bragg mirrors (12, 14), the cavity (16) comprising an optical filter (18) and an active medium (20),the method comprising the steps of: measuring the temperature of the active medium (20),setting the temperature of the optical filter (18) in accordance with the measured temperature of the active medium (20), the temperature of the optical filter (18) being higher than the measured temperature. | ||

| 主权项 | 1. A method for controlling the emitting wavelength of a laser source for a passive optical network, the laser source comprising: a first Bragg mirror, a second Bragg mirror, a cavity delimited by both Bragg mirrors the cavity comprising an optical filter and an active medium, the method comprising the steps of: measuring the temperature of the active medium,setting the temperature of the optical filter in accordance with the measured temperature of the active medium, the temperature of the optical filter being higher than the measured temperature;wherein the method further comprises a step of comparing the measured temperature of the active medium with at least two main temperature thresholds. | ||
