We describe a novel photoluminescence measurement apparatus which incorporates an optical fiber for carrying both the excitation beam and the luminescence from the sample. The advantages of the optical fiber makes the system very versatile and suitable for sensitive measurements. The collection efficiency of the setup is demonstrated to be the same as that of a conventional setup. Several photoluminescence spectra of III-V compounds recorded using the apparatus are also included to demonstrate its applicability over a wide wavelength range (0.8-2.0 μm).
