BiVCSEL operation at 925 and 955 nm

We present a monolithically integrated coupled cavity vertical cavity surface emitting laser or BiVCSEL: this two-terminal electrically injected device exhibits stable laser emission at two design wavelengths simultaneously. The coupling between the two monolithically grown cavities leads to two distinct Fabry-Perot modes whose separation and localization are designed in such a way that the interaction between the two modes leads to dual laser emission. Simultaneous lasing at 925 nm and 955 nm is achieved experimentally with a threshold for dual lasing of 4 kA/cm(2) and dual lasing is stable over 6 times threshold.
