摘要：

We have constructed a variable spectral-width, wavelength-tunable light source using a non-fiber-coupled broadband superluminescent diode device with an optical feedback mechanism. As lasing occurs, a strong output light which is linearly polarized and monochromatic is obtained. The spectral width varies with the injection current and the optical feedback ratio. By incorporating a dispersing prism into the feedback branch, a wavelength-tunable, external-cavity-feedback laser source is achieved. The result is a convenient, inexpensive apparatus suitable for experiments in undergraduate optics courses. (c) 2008 American Association of Physics Teachers.
