Abstract

We report on an experiment to study the properties of subthreshold modes of a multiple quantum well diode laser in an external grating cavity configuration. Measurement of the radio frequency (rf) intensity noise near the external cavity mode spacing provides information about the intensity and phases of the adjacent subthreshold modes. The rf spectrum has a double peaked structure, as has been previously reported; and we also measure optical spectra with a Fabry-Perot etalon to isolate the individual side modes. In addition, we observe rf noise and optical spectra at higher multiples of the external cavity mode spacing. Our data are compared with previous theoretical models.
