Webnl-nl.facebook.com WebAbstract: We report the first optical gain measurements on InGaAsP/ InP double heterostructures with composition corresponding to an emission wavelength of about 1.3 μm at 300 K. At optical pumping levels of about 1 MW/cm 2 the maximum gain values of the best samples available are 800 cm -1 at 2 K, 500 cm -1 at 77 K, and 200 cm -1 at 300 K.
