Abstract
A magnetic recording device comprises a multi-aperture vertical cavity surface emitting laser (VCSEL) operably coupled to a magnetic recording head and a plurality of waveguides disposed in the magnetic recording head. Each of the plurality of waveguides has a first end coupled to a different aperture of the multi-aperture VCSEL. The magnetic recording device further comprises a near field transducer disposed in the magnetic recording head. Each of the plurality of waveguides has a second end coupled to the near field transducer.
