MESA/TRENCH FREE VERTICAL CAVITY SURFACE EMITTING LASER (VCSEL) - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022045 titled 'MESA/TRENCH FREE VERTICAL CAVITY SURFACE EMITTING LASER (VCSEL)
Simplified Explanation
The abstract describes a patent application for a vertical-cavity surface-emitting laser (VCSEL) that has improved heat dissipation compared to conventional VCSELs. The VCSEL includes a first reflector, a second reflector, and an active region between them. The first reflector has a characteristic dimension in a plane perpendicular to the emission axis, as does the second reflector. These characteristic dimensions are equal, which enables better heat dissipation.
- The patent application is for a vertical-cavity surface-emitting laser (VCSEL) design.
- The VCSEL includes a first reflector, a second reflector, and an active region.
- The first reflector and the second reflector have characteristic dimensions in planes perpendicular to the emission axis.
- The characteristic dimensions of the first and second reflectors are equal.

Original Abstract Submitted
a vertical-cavity surface-emitting laser (vcsel) is provided that includes a first reflector; a second reflector; and an active region disposed between the first reflector and the second reflector. the first reflector defines a first reflector characteristic dimension in a plane that is substantially perpendicular to an emission axis of the vcsel, and the second reflector defines a second reflector characteristic dimension in a plane that is substantially perpendicular to the emission axis. the first reflector characteristic dimension is substantially equal to the second reflector characteristic dimension, which enables the vcsel to exhibit improved heat dissipation compared to conventional vcsels.
