Phase-locked arrays of surface-emitting graded-photonic-heterostructure terahertz semiconductor lasers.

چکیده
We have demonstrated that a hybrid laser array, combining graded-photonic-heterostructure terahertz semiconductor lasers with a ring resonator, allows the relative phase (either symmetric or anti-symmetric) between the sources to be fixed by design. We have successfully phase-locked up to five separate lasers. Compared with a single device, we achieved a clear narrowing of the output beam profile.

Phase-locked laser arrays through global antenna mutual coupling
Phase locking of an array of lasers is a highly effective method in beam shaping because it increases the output power and reduces the lasing threshold. Here, we show a conceptually novel phase-locking mechanism based on ‘antenna mutual coupling’ in which laser elements interact through far-field radiations with definite phase relations. This allows a longrange global coupling among the array e...
متن کاملMass - Transported GaInAsP / InP Lasers
A new microfabrication technique, mass transport, has made possible the development of a new breed of semiconductor laser devices. Mass-transported buried-heterostructure GaInAsP lasers are ideally suited for application in optical-fiber communication systems. In fact, the technology for mass-transported buried-heterostructure lasers has been transferred to a commercial fabricator, and these la...

متن کاملCoherent coupling of two-dimensional arrays of defect cavities in photonic crystal vertical cavity surface-emitting lasers
An approach for creating two-dimensional arrays of coherently coupled vertically emitting laser cavities is demonstrated. This is achieved by creating a 232 array of defect cavities within the top distributed Bragg reflector of a photonic crystal vertical cavity surface-emitting laser. The optical coupling occurs laterally through coupling regions defined between the defect cavities. Modifying ...
