Tunable semiconductor diode laser with distributed reflection

摘要: A tunable semiconductor diode laser with distributed reflection (DBR laser) having a wide wavelength range is suitable transmitter or local oscillator in receiver heterodyne and coherent optical glass fiber communication systems. Such includes, addition to the Bragg section which takes place, an active radiation-emitting region present. When such further provided so-called phase section, tuning possible over large within one oscillation mode. continuously whole obtained by mechanism intensity of radiation reflected at junction between made low respect returns from section.
