Wavelength stabilization of broadband semiconductor light sources.
A two-beam interferometric technique is described for stabilizing the wavelength of a broadband ( approximately 10-nm) semiconductor light source-a GaAs/GaAlAs superluminescence diode. Preliminary results show that the wave-length can be stabilized to better than 1 part in 10(6) for an averaging time of 1 sec.
