Gain enhancement of perovskite nanosheets by a patterned waveguide: excitation and temperature dependence of gain saturation
Optical gain enhancement of two-dimensional CsPbBr<sub>3</sub> nanosheets was studied when the amplified spontaneous emission is guided by a patterned structure of polyurethane-acrylate. Given the uncertainties and pitfalls in retrieving a gain coefficient from the variable stripe length...
