We propose and analyze an active mirror structure that uses a subwavelength grating reflector combined with optical gain. The structure is designed to be directly bonded to a thermal substrate (such as diamond) for efficient heat removal. We present optical wave propagation and thermal transport analysis and show that such a structure is well suited for power scaling of optically pumped semiconductor disk lasers to multi-kilowatt CW power operation.
