Enhanced photoluminescence at a wavelength as high as 5 μm is obtained in uni-axial tensile strained GeOI micro-bridges cavities. We present, using excitation power dependent photoluminescence spectroscopy, a clear cavity mode pattern which indicates a loss reduction with increasing free carrier density.
