Narrow-linewidth single-mode vertical-cavity surface-emitting laser
Abstract
A coupled-cavity vertical-cavity surface-emitting laser (VCSEL) is disclosed. The coupled-cavity VCSEL includes a passive cavity and an additional distributed Bragg Reflector (DBR) not found in conventional VCSELs, all in a monolithic device. By including these two elements, the photon lifetime may be increased by a factor of approximately ten, leading to a reduction in the laser linewidth by a factor of approximately 100 compared to conventional VCSELs. The two additional elements also serve to ensure single-mode operation of the coupled-cavity VCSEL.
