Abstract: An internally-modulated laser in which first, second and third reflectors and a polarization means are oriented with respect to each other both to provide a first optical resonant cavity, defined by the first and second reflectors, and a second optical resonant cavity, defined by the first and third reflectors. A laser medium is located in the common portion of the cavities between the first reflector and the polarization means, and an individual data-signal-responsive modulator is situated in each respective individual portion of the cavities between the polarization means and the respective second or third reflector. The first cavity supports a given polarization and the second cavity supports a polarization orthogonal to the given polarization. The modulated output wave energy provided by this apparatus includes two separate orthogonally polarized data channels.
