Abstract
This disclosure describes a multi-junction laser diode with improved wavelength stability. The multi-junction laser diode is found in an edge emitting laser (EEL). The disclosed system and method are suited for improving the wavelength stability of multi-junction EEL without coupling the laser modes of the individual junctions and without using any external elements such as Fiber Bragg Gratings (FBR), Volume Bragg Gratings (VBG) or Thermoelectric Cooling (TEC).
Claims19
A system, the system comprising:
- a laser diode comprising:
- a laser cavity comprising one or more lasing junctions;
- a first mirror on a first facet of the laser cavity;
- and
- a second mirror on a second facet of the laser cavity, wherein a reflectivity of at least one of the first mirror and the second mirror is variable over wavelength.
2 more elements
A method, the method comprising:
- forming a laser cavity via one or more lasing junctions;
- depositing a first mirror on a first facet of the laser cavity;
- depositing a second mirror on a second facet, wherein a reflectivity of at least one of the first mirror and the second mirror is variable over wavelength;
- and
- generating a feedback, in the laser cavity, between the first mirror and the second mirror.
