LASER ARRAY FOR HEAT ASSISTED MAGNETIC RECORDING

LASER ARRAY FOR HEAT ASSISTED MAGNETIC RECORDING

An apparatus comprises a unitary laser diode comprising an array of two or more active regions, at least one of which outputs a light beam in response to an input current. The apparatus also includes two or more waveguides, each waveguide corresponding to an active region of the array. At least one...

Zusammenfassung:An apparatus comprises a unitary laser diode comprising an array of two or more active regions, at least one of which outputs a light beam in response to an input current. The apparatus also includes two or more waveguides, each waveguide corresponding to an active region of the array. At least one of the waveguides receives the at least one light beam from the at least one active region.
